Topics covered

Task of defining the research problem is the preparation of the research project, popularly known as the ‘’research design”.

Decisions regarding what, where, when, how much, by what means concerning an inquiry or a research study constitute a research design.

WHAT IS RESEARCH DESIGN?

The preparation of such design facilitates research to be as efficient as possible yielding maximal information . In other words , the function of research of research design is to provide for the collection of relevant evidence with minimal expenditure of effort, time and money.

Meaning of research design

The design which minimise bias and maximise the reliability of data collected and analysed is considered a good design.

Though there are following factors which are considered in a good design:-

The means of obtaining information .The availability and skills of the researcher

and his staff, if any;

Features of a good research design

The objective of the problem to be studied;The nature of the problem to be studied; andThe availability of time and money for the

research work.

Different research design

Exploratory research method are also termed as formulative research method.

The main purpose is that of formulate the research problem there are three methods:-

i. The survey of concerning literatureii. The experience surveyiii. The analysis of ‘insight – stimulating’

Exploratory research design

The most simple and fruitful method of formulating the research problem or developing hypothesis.

Hypothesis stated by earlier workers may be reviewed and their usefulness be evaluated as a basis for further research. The already stated hypothesis suggest new hypothesis. The researcher should review and build upon the work already done by others.

1. The survey of concerning literature

Experience survey means the survey of people who have had practical experience with the problem to be studied.

The object of such survey is to obtain insight into the relationship between variable and new ideas relating to research problem.

2. The experience survey

It is also a fruitful method of suggesting the hypothesis . It is particularly suitable in the areas where there is little experience to serve as a guide.

In this method the existing records may be examined.

3. The analysis of ‘insight-stimulating’

In case of descriptive research study determine one those studied which are concerned with describing the characteristics of a particular individual or a group.

In diagnostic research study determine the frequency which something occur or its association with something else.

The design should be rigid and not flexible.

Descriptive and Diagnostic research

a) Formulating the objective of the study.b) Designing the method of data collection.c) Selecting the sample.d) Collection the data.e) Processing and analysing the data.f) Report the finding.

The design must focus attention on the following:-

It is generally known as experimental studies

It is a research studies where the researcher tests the hypotheses of casual relationships between variables. Such studies require procedure that will not only reduce bias and increase reliability , but will permit drawing inference about causality .

Hypothesis- testing research studies
