5. WHAT IS QUANTITATIVE RESEARCH?Quantitative Research Is "a formal, objective, systematic process in whichnumerical data are utilised to obtain information about the world“. It is inclined tobe deductive. In other words it tests theory.GENERAL AIMS OF QUANTITATIVE RESEARCH? To Generalize To Be Objectives To Test Theories or Hypotheses
6. STRATEGIES ASSOCIATED WITH QUANTITATIVE APPROACHEXPERIMENTAL Experimental research provides a framework for establishing a relationship between causes and effects. In experimental the researcher acts as a inactive agent and use deductive reasoning to prove or falsify hypothesis. This involves manipulating an independent variable (cause) and observing the outcome on dependent variable (effect) while controlling the extraneous variables. Moreover, random sampling, manipulation and control are the characteristics of the true experiments.SURVEYS Surveys include cross-sectional and longitudinal studies using questionnaires or structured interviews for data collection, with the intent of generalizing from a sample to a population

8. WHAT IS QUALITATIVE RESEARCH? Qualitative Research Is “an informal, subjective research approach that usually emphasizes words rather than numbers in the collection and analysis of data” and that is inductive in nature. In other words it generates theory.GENERAL AIMS OF QUALITATIVE RESEARCH? To add understanding to a phenomenon or the complexities of human behavior It does not claim to generalize To generate theory therefore it is inductive rather than deductive
9. STRATEGIES ASSOCIATED WITH THE QUALITATIVE APPROACH? Attempts to shed light on a phenomenon by studying in depth a singleCase Study case example of the phenomena. The case can be an individual person, an event, a group, or an institution.Grounded Theory is developed inductively from a corpus of data acquired by aTheory participant-observer. Describes the structures of experience as they present themselves toPhenomenology consciousness, without recourse to theory, deduction, or assumptions from other disciplines Focuses on the sociology of meaning through close field observation ofEthnography socio-cultural phenomena. Typically, the ethnographer focuses on a community. A from of inquiry in which the researcher studies the lives of individual and ask one or more to provide stories about their lives and in the end, theNarrative narrative combine views from the participants’ life with those of researcher’s life in a collaborative narrative.

Interpretation of Data 5. Conceptual and Theoretical Work 5b. Tighter Specification of the Research Question (s) 6. Writing up Findings/Conclusions
11. THE BASIC PROCESS OF QUANTITATIVE AND QUALITATIVE RESEARCH? Another preliminary consideration before designing and conducting research is to review and know the basic elements of both quantitative and qualitative research so that to choose an appropriate approach. These elements are discussed in the next table.

14. MIXED METHODS APPROACHA mixed methods approach is one in which the researcher tends to base knowledgeclaims on pragmatic grounds (e.g., consequence-oriented, problem-centered, andpluralistic). It employs strategies of inquiry that involve collecting data eithersimultaneously or sequentially to best understand research problem. The datacollection also involve gathering both numeric information (e.g., on instruments) aswell as text information (e.g., on interview) so that the final database representsboth quantitative and qualitative information.
15. STRATEGIES ASSOCIATED WITH THE MIXED METHODS APPROACH Sequential procedures, in which the researcher seeks to elaborate on or expand the findings of one method with another method. This may involve beginning with a qualitative method forSequential Procedures exploratory purposes and following up with a quantitative method with a large sample so that the researcher can generalize results to a population. Alternatively, the study may begin with a qualitative method involving detailed exploration with a few cases or individuals. Concurrent procedures, in which the researcher converges quantitative and qualitative data in order to provide a comprehensive analysis of the research problem. In this design, the investigator collects both forms of data at the same time during the study and then integrates the informationConcurrent Procedures in the interpretation of the overall results. Also, in this design, the researcher nests one from the data within another, larger data collection procedure in order to analyze different questions or levels of units in an organization. This strategy involve the data collection either through sequential or a con-current approach, butTransformative after the initial analysis, there searcher uses procedure to transform one data type into the otherProcedures data type. This is accomplishing result which facilitates comparison, interrelation and further analysis of two data sets.
