Chapter two addressing the types of variables deployed in a study. Either, chapter three tells how to generate research idea. Rather, the book through chapter four described how to develop a researchable topics. Meanwhile chapter five gives explanation on how to carry out literature survey that forms a crucial party of studies. Then chapter six is critically explain research designs and research management.

The book concludes with the application of computer software in research process. We take our hats to thank each of them because of their tremendous contribution on this research knowledge. We also want to acknowledge our families for their sponsorship and material time during the journey to publish this book.

We sincerely thank Dr Fredrick Odoyo to edit the manuscripts of this book. Either, we appreciate contributions and expert advice made by Dr Richard Nyangosi from St. George B.

Africanus C. These techniques are used to collect secondly and primary information regarded to a topic, Kothari On the other hand Merrian-Webster described a research as hierarchy of actions toward investigation for the purpose of knowledge gain from new facts discovery. Either Zickmund added that, this systematic investigation can be on either existing or new knowledge. Whereby the knowledge found can be used to lay a foundation to prove facts, or contribution to expansion on results of previous works and resolve existing problems.

Likewise the process supports confirmation of existing theorems as well as developing new theories. Also a study can be conducted to test instrument validity and research process, prior projects to justify available gap from the previous research work.

Business Research Methodology

Evaluation research According to Robson evaluation is described as a distinctive purpose that is not research strategy. So far, Patton refers evaluation research as a process involving scanning activities, characteristics and outcomes to reduce uncertainties and improve effectiveness on certain matters. The concentration is to know what changes caused by the interventions. Therefore, the decision to undertake further action depends on impact that; is measured through specific measurements. Whereby, this method of enquiry attempts to reveal the real value on specific interventions.

Evaluation by itself is not necessarily a research, but it involves some elements of systematic process to achieve answers. Furthermore, Draper argued that; the outcome of doing evaluation enquiry based on its implication to know why the study is conducted. The assessment process needs to involve the evaluation criteria and highlight areas to make changes. This approach suits the situation where the study is limited by tight deadlines or limited timing.

These approaches vary from their scope; they are either broad or specific in nature. Some of researches which are similar to the scope of qualitative research are namely field research and naturalistic research.

But the specific ones are interpretive research and ethnographic research. A Qualitative research approach deals with systematic and in-depth investigation of events in natural settings. In most cases qualitative techniques use data in the form of description. These data are collected from interviews, written observations and conversations. In other words the qualitative research includes tools which can make critical assessment.

Example qualitative research can be used to examine emotional issues such as thought and feelings. Thus, mechanisms such as observation, interview and document review are deployed to analyze situation. In order to get to core of the phenomenon and answer critical question like why a certain problem is happening.

Whereas, the study can manage to provide in-depth knowledge about issues and create discovery Strauss and Corbin, Furthermore; this research enquiry has the ability to scan, interpret situation and remains as natural research.

On the other hand the study done by Sarantakos says that, this type of study argued as communicative. In such a way it allows researchers to interact with participants for the purpose of contemplating and reflect issues related to the study.

But, apart from the benefits this type of enquiry has some limitations such as subjectivity and relativism. Thus, it can involve stereo typing and value judgment elements on conclusion and results.

Therefore, it can lead into biasness this is one of the reason why most of researchers prefer triangulation. It means the researchers can make use of both qualitative and quantitative approaches. Mwanje, Qualitative research is one of the inquiry methods that can be used in various disciplines, especially in the social sciences.

This research approach tends to collect in-depth data related to human behavior as well analyzing theories which govern that behavior. Rather the technique helps to answer principle questions such as why or how in order to reach conclusions.

It is possible to achieve objectivity through a focused and small sample. On the other side, qualitative techniques are used to information and opinion for particular cases understudy to make general conclusions. Meanwhile, quantitative methods are often helpful to gather empirical facts support developed from hypotheses. For instance, in social sciences the qualitative research is usually used to conduct ethnographic studies. Whereby cultural studies are examined critically, data are gathered and described for the purpose of theory development.

Hence, the study involves critical analysis on what the people eat and wear. Other study types supported by qualitative approach include ethical studies, which are conducted to evaluate choices for doing wrong or right and its obligation. Either qualitative approach deals with foundational research, from which the science principles are analyzed. It is carried out to lay a foundation on how to adopt changes on existing information based on new knowledge.

The other qualitative approach is based on historical studies, it helps making discussion both past as well as present events base on context. Example, conducting examination on current situation and reflect the trends. The historical study meant to fill the gap for fundamental question such as when did it happen and when is it going to happen? According to Tufte explains that, in recent days a qualitative research approach is quite often used in evaluation studies.

For example, studies like evaluation of computer system analysis and humanity studies. Rather, the qualitative research approach apart from being conducted in natural settings. It collects data in the form of wording instead of numbers, through observation, in-depth interviews and documents review.

In other cases it deploys hypotheses from which the study tends to understand individuals targeted population and the situation setting. Whereas qualitative method needs to be complemented by a quantitative method in order to conduct a particular study. Apart from qualitative study, the quantitative method is normally used in questions tend to evaluate specific situations setting.

That remains static till the end of study. Similarly, it is difficult to evaluate the dynamism of the given phenomenon. This is the reason why qualitative research methods are playing a crucial role in dynamic situation as compared to quantative methods. It goes beyond what and how on certain situations.

But, trying to understand why it is happening. Determining to assess the meaning or context in which a certain events caused phenomena in natural setting Wolcott, Thus, the qualitative studies tend to determine what the study measurements are, and why they are useful in measuring the study results. Similarly, it tries to understand what is happening and why as well as assess how and why people feel on the subject matter.

It evaluates the implications of influence on social, organizational and cultural matters towards the study. Likewise, the study is deployed to confirm if the causal relationships exist. Rather qualitative research approach is generally concerned with qualitative phenomenon. For instance, studies involved on assessing issues related with quality as well as categories. Or studies interested to generate reasons for a certain behavior e.

Hence, a motivation study can be deployed to find out the reasons underlying the factors involved. This research tries to explore the motives and desires by conducting in depth analysis, evaluation and interviews. Apart from interviews the qualitative research involves various tests in form of wording both oral and written.

Bibliographic Information

The purpose for undertaking these tests is examined attitude or individual opinion toward the research. So, study expectation is to find out, how individual feels, think and about the subject matter.

Quantitative research The quantitative research involves a systematic empirical investigation of issues using statistical, mathematical as well numeric approach. Mainly the quantitative design applies models, hypotheses and theorem which are related to the problem. But Huisman on the other hand comments that, this process is guided by established measurements in numerical forms. Thus, quantitative study relates empirical observation with the given mathematical expressions. In this case, quantitative data are those given in the form of numerical.

For example statistics such: as mean average , percentages and standard deviation.

Then, data collected are analyzed through statistical approach, in order to achieve research objectivity from the sample results that are generalizing the targeted population. Thus, a quantitative study is determining to express measurements for given phenomena in form of quantities or specified amount. Unlike qualitative research which tends to ask questions with expectation to collect explanation data wording from respondents.

This kind of research approach targeting on information that describes phenomena in patterns way of the participants. Furthermore, in most cases the quantitative research used quite often in social studies likes psychology, economics and sociology to mention a few.

But not in studies related to anthropology and history, because in most cases they tend to collect data in form of descriptions. Either the quantitative Research widely used in mathematical sciences like physics. Whereby, researchers are interested to gather data that define quantities. On the other hand the social scientist, the approach is related to empirical study approach. This makes a distinction between qualitative research methods from quantitative approach.

Usually, qualitative techniques generate information hypotheses from specific studied cases for general conclusions. This is due to the reason that, examination, analysis and findings interpretation from observation done through qualitative process does not include mathematical models.

According to the nature of qualitative data, it not necessary to deploy statistical tools in order to analyse the data collected from the field.

In other words, they are not easily quantified or put in numeric form. In this case examinations are carried out to describe relationship between cause and the phenomena through identified meanings and patterns.

Triangulation research In most cases the triangulation research approach referred to various methods used to achieve both study finding and conclusion. Its purpose is to create a mechanism to validate and check the results. That means the study deploys multiple data collection techniques which depend on researchers combinations. These wide ranges of study techniques tend increase to strength of the findings through cross validation.

However, this convergence of different research methods is also creating data credibility and congruent to its sources. If the data tends to diverge then the assumption is that, there is a gap within the explanation given by research participants. Building on this assumption the researchers need to be confident with the findings developed from Triangulation research.

Because the researcher is able to verify, validate and fill the weakness caused in any of the methods. So the applications of various study strategies in order to achieve study objectivity and reliability Thompson, Deductive approach A deductive study approach helps a researcher to develop hypotheses through application of theory s. Where by researchers collect field data or facts are collected to test the position of research by rejecting or accept the hypotheses developed.

Gill and Johnson, The process involves different steps in order to perform a deductive research approach, it starts with a theory, and then the hypotheses are developed according to the given theory. Followed by observation, from which collected data or facts are used to confirm the situation.

On the other side, the inductive research process is the opposite of deductive. Because the process starts with observing the situation, examining patterns in order to create tentative hypotheses.

After the whole process is done, then hypotheses are used to build up a theory. See the figure below Deductive approach diagram illustration not visible in this excerpt Source: Qureshi Deductive is characterised by study description through conceptual development as well theoretical structure, from ideas and facts are tested or verified.

That mean inferences alternative solutions developed are filtered from general instances, and come with a single solution. In other words this method is "top-down" approach, from which the study thoughts are guided by general to specific approach Crowther and Lancaster However, a deductive study approach tries to guide researchers thought.

Whereas the general knowledge about the theory, taken into specific hypotheses. Meanwhile, the developed hypotheses are tested through specific methods and make conclusion on recorded facts to prove right or wrong. The study can approach general problems and specify issues related to a given problem.

Examine assumption developed from observation in order to prove hypotheses. Ritchie and Lewis Inductive approach Either the Inductive research approach is mainly guiding the researchers thought.

Where the study approach explains how to deal with specific observations, and changes them to general theory. For instance if there is a phenomena observed within the community in a pattern way, then hypotheses are developed and examined through specific methods to conclude.

This research process is not rigid in nature. That means the process does not require pre-determined theories on data collection flexibility. Therefore, researchers are able to generate their observations on various matters or experiences Mertens Inductive approach is subjective in nature, whereby researchers can come out with their own interpretation. Ridenour, Benz and Newman Inductive research approach diagram illustration not visible in this excerpt Source: Trochim The diagram given above describes how a study takes different steps to develop a theory.

Just from observation, were the general inferences are created to form issues under the study from which particular instances are taken to conclude the study. In this particular approach the study results comes from a logical process in which matters are specified and clearly stated. Hence, the end result is to create a predictive framework for resolving matters of specific condition or factors.

Therefore thoughts are guided in order to deal with specific observations in order to create a wide knowledge general conclusions. Deductive and Inductive Approach diagram illustration not visible in this excerpt Source: Trochim Inductive and Deductive study approaches Conclusively, the two study approaches discussed and shown in the figure above i.

They are essential since, both of them trying to increase efficiency in investigation and research process. But, these approaches are distinct to each other. For instance, the deductive study paradigm is mainly targeting to achieve positive conclusion solution to a problem , where there is alternative solutions. Whereas the inductive research paradigm, targets to interpret phenomena and create knowledge.

Therefore, choices for appropriate research paradigms depend on the nature of study as well as researchers expectations on the conclusion. Saunders et al comments that, both approaches help estimation to determine the logical process as well as study results synthesis.

Research types The fundamental research types are as follows: Descriptive vs. Analytical : Descriptive research involves doing surveys as well as searching facts on different phenomenon through enquiries.

Purposively the descriptive research deals with description of existing or current situation. Either, Rosnow and Rosenthal argued that, this kind of study approach deployed in social science disciplines in order to examine and describe consequences caused by existing issues.

In other words this type of research is called Ex post facto study. Likewise in this type of enquiry researchers have less control on variables, because it can allow explaining what happens and ongoing situation. Hence researchers examine cases through descriptive studies with the intention to measure and analyze the situation.

For instance, frequencies can be used as a measure to describe data such as behavior, attitude and intention as well as people preferences. The data found on Ex post facto studies also tries to show and helps to identify causes in relation to existing problems, though researchers are limited over variables control. Here are some of techniques used in descriptive approach; it includes survey, comparative as well as correlation techniques.

But, in analytical approach researchers examine facts or analyze the given information to make conclusion. Applied vs. Fundamental: The applied research is carried out to reach on conclusion and enhance the decision making process. The approach helps to identify the best alternative action among the pool of actions. It tries to explore factors and its implication, where there is no specific action to resolve the existing problem.

But for the fundamental or basic and sometime is called pure research. Example, problem related to business growth or cholera outbreak in the community.

The process involves gathering data describe phenomenon in order to create awareness or provide guidance. Tentatively the approach is known as pure, basic or fundamental research.

For instance conducting a study about the universe or natural phenomenon, that involves creation of either mathematical expression or formulae.

Likewise, deploying studies related to human or human behavior, are type of researches need to view a specific community in pattern way. From which some factors are related and it is possible to generalize. Traditionally the pure research used to make contribution on existing knowledge.

Likewise, it helps to conduct research for the purpose of developing theory s. This research type is not used to resolve the problems, but to seek information and create knowledge or theories. Rather it is deployed to explore or gathering facts in order to make clarifications on phenomenon, usually this type of research is used to conduct scientific studies research. Meanwhile, all research aiming at achieving a certain conclusion or specific solutions, are identified as applied research.

For instance principle question like how to achieve business sustainability or strategic decisions, are examples of applied research. A research which is conducted to examine factors as well its influence leading a specific situation. For instance, evaluation research is one of the typical examples of applied research. Thus, applied research is motivated by discoveries, from which the problem understudy achieves its own solution Collins, In applied study approach, the research findings are put under application Action Research in order to improve the existing situation problem.

The process tries to relate the problem understudy with cause as well as its effect. Thus, from the findings researchers are able to conclude or achieve the best alternative solution to deal with the cause.Louis Cohen.

Similarly, it is difficult to evaluate the dynamism of the given phenomenon. Mette L. For instance, a research study about consumer behavior is subjected to cultural belief factor among other factors which affect the consumer attitude. For instance, in social sciences the qualitative research is usually used to conduct ethnographic studies. Read more In most cases a research intends to overcome issues which cause problems to a community. A research which is conducted to examine factors as well its influence leading a specific situation.

The process tries to relate the problem understudy with cause as well as its effect. Sometimes, it involves things which need clarification from researchers or more knowledge towards existing phenomenon.
