RESEARCH DESIGN

INTRODUCTION

Decisions regarding What , Where , When , How much by what means concerning a research project constitute a research design.

Research Design is the arrangement of conditions for collection and analysis of data in a manner that aims to combine relevance to the research purpose with economy in procedure.

Research Design is the conceptual structure within which Research is concluded.

DEFINITIONS OF RESEARCH DESIGN

“It is the plan structure and strategy of investigation conceived so as to obtain answers to research questions and control variance.”

FRED N. KERLINGER

“Research design are plans that specify how data should be collected and analyzed.”

REGER E. KIRK

FEATURES OF A GOOD DESIGN

1) Need for the study

2) Review of previous study

3) Statement of problems

4) Objectives of study

5) Formulation of hypothesis

6) Operational definitions

7) Scope of the study

8) Time estimates

9) Financial budget

TYPES OF RESEARCH DESIGN

Experimental Research Design

Exploratory Research Design

Descriptive Research Design

I] Experimental Research Design :- It refers to that research

process in which one or more variable are manipulated under conditions that permit the collection of data that shows the effect, if any, such variable in unconfused fashion.

Basic principles of Experimental Design

i) Principle of Replication

ii) Principle of Randomization

iii) Principle of Local Control

Principle of Replication :- In this design the experiment should be

repeated more than once. Thus, each treatment is applied in many experimental units instead of one.Ex- examine the effect of two varieties of rice.

Principle of Randomization :- This principles indicates that we

should design or plan the experiment in such a way that the variations caused by extraneous factor can all be combined under the general heading of “chance.”

Principle of Local Control :-Under it the extraneous factor , the known

source of variability ,Is made to vary deliberately over as wide a range as necessary and these need to be done in such a way that the variability it causes cab be measured & hence eliminated from the experimental error.

According to this principle we first divide the field into several homogeneous parts known as blocks and then each such block is divided into parts equal to the number of treatment.

II] Exploratory Research Design:- Exploratory research helps ensure

that a rigorous & conclusive study will not begin an inadequate understanding of the nature of the business problem.

Exploratory research may be a single research investigation or it may be a series of informal studies both method provide background information.

Purpose for conducting Exploratory research

A) Diagnosing a situationB) Screening alternativesC) Discovering new ideas

Categories of Exploratory research

A) Experience surveysB) Secondary data analysisC) Case Study methodD) Pilot studies

III] Descriptive Research Design :- Descriptive Research involves

gathering data that describes event and then organizes, tabulates,

depicts and describe the data collection. Descriptive Statistics are very important in reducing the

data to manageable form.

Descriptive function of research is heavily dependent on instrumentation for measurement and observation.

Descriptive research design have come to be viewed and acknowledged as the different survey method available to research for collecting quantitative primary data from large groups of people through the questions & answer protocol process.

Descriptive Technique includes

1) Graphical description

2) Tabular description

3) Parametric description

4) Measures of location or Central tendency

Role Of Research Analyst

A research analyst is someone who is responsible for reviewing large amount of data and analyzing the information using a variety of software tools and methodologies.

There are four requirements for a research analyst

i) Post secondary education

ii) Experience

iii) Critical thinking skill

iv) Technical skill

General objectives of Managerial Research analyst are as follow

•Decision making objectives

• Economic & business objectives

• Policy objectives

• Product development

• Profit objectives

• Human Resource Development objectives

• Market objectives

• Innovation objectives

• Customer satisfaction objectives

• Promotional objectives

• Corporate change objectives
