Chapter 10 Research Design
The purpose is to elucidate & justify the methodological approach used. It examines the assumptions underlying the use of a particular research design & provides arguments for the preference of one over another.
Research Approach
Descriptive
The purpose is to provide a clear picture of specific issues, to describe the characteristics of certain research problems, & to make prediction of the social phenomena
Rigid & requires a clear & precise specification of research question
Involves large proportion of social science research
Causal
This type of study is appropriate to show relationship between variable involved in the research framework.
Hypothesis testing in quantitative analysis has the capability to explain the type of relationship.
Based on the principle of causality which gives emphasis to the relationship between cause & effect.
Explotary
Helpful in breaking broad, imprecise problem statements into smaller & more precise sub-problem statements
Used to establish priorities among research questions & for learning about practical problems of carrying out the research.
Aims to gain insight & ideas
Research Design I
Correlational study
A study of the relationship between one or more independent variable & one or more dependent variable
It produce different kind of data, involves different statistical analyses, treat all participants as a single group & measures two variable individually
Cross-Sectional study
It divides people into different groups, data collected at a single time from these groups & findings from data analysis are compared between these two group.
Survey
Participants are selected randomly from sample can represent the characteristics of studied population
Survey is flexible procedure because data can be collected via various techniques.
Longitudinal study
It is used to continue studies about particular issues that have been done previously.
Case study
Allow a researcher to investigate a particular problem in detail and intensive within a certain period of time.
Able to investigate individuals / programs changes affected by certain interventaions
Grounded theory
It is a method of developing a theory based on data collected from the field study setting.
This study is good if current theories about a particular phenomenon are non-existent.
Research design play an important role in determining the most appropriate research framework to conduct research activities. It is a job of the researcher to define & chose the most appropriate one.
Research Design II
Experimental design
Often used to investigate a direct relationship between two variable
Four basic components
Measurements
Comparisons
Manipulation
Control
True experiments
Refers to completely control all aspects in an experiments which means who, what, when, where & how an experiments is conducted wholly controlled by a researcher
Comparative design
It helps to understand social phenomenon by comparing two ore more contrasting cases.
This research normally begins with deductive approach
Quasi experiments
It explains that a researcher is not able to control all aspects while conducting experiments
Action research
To increase the ability of the involved organisation member to control their own objectives more effectively
To keep improving the capability to achieve their objectives
Ethnography
An in-depth approach of study a group of people that share a common culture in a natural setting for a long period of time
