A Power Point Presentation on “ RESEARCH DESIGN”

RESEARCH DESIGN: 

RESEARCH DESIGN The research design is the master plan specifying the methods and procedures for collecting and analyzing the needed information. Three traditional categories of research design -: Exploratory Descriptive Casual The choice of the most appropriate design depends largely on the objectives of the research and how much is known about the problem and these objectives.

EXPLORATORY RESEARCH: 

EXPLORATORY RESEARCH Exploratory research is a type of research conducted for a problem that has not been clearly defined. To gain background information about the general nature of the research problem. The researcher does not know much about the problem and needs additional information or desires new or more recent information. To develop HYPOTHESES or QUESTIONS TO BE ANSWERED.

Slide 4: 

A variety of methods are available to conduct exploratory research: Secondary Data Analysis Experience Surveys Case Analysis Focus Groups Projective Techniques Internet (Google Alerts, Google Trends, RSS Feeds)

DESCRIPTIVE RESEARCH: 

DESCRIPTIVE RESEARCH Describes the various characteristics of the phenomenon being studied. Provide answers to questions of who, what, where, when, and how? Two basic classifications: Cross-sectional studies Involve observation of all of a population, or a representative subset(sample), at a defined time. Sample Surveys, Online Research Surveys

Slide 6: 

Longitudinal studies A correlational research study that involves repeated observations of the same items(sample) over long periods of time. Cohort Studies sample a cohort, (defined as a group experiencing some event) in a selected time period, and studying them at intervals through time(long term intervals). Panel Studies sample a panel, and the same panel is asked to respond periodically, usually at regular intervals. Longitudinal data used for: Market tracking Brand-switching Attitude and image checks

CAUSAL RESEARCH: 

CAUSAL RESEARCH Causal Research explores the effect of one thing on another and more specifically, the effect of one variable on another. It involves the measuring of the CAUSE and EFFECT Relationship between two variables X and Y.

Slide 8: 

There has to be proper recognition of the X and Y variables and their nature, i.e. either being Dependent variable, Independent variable or Extraneous variable. Independent variables: those over which the researcher has control and wishes to manipulate i.e. package size, ad copy, price. Dependent variables: those over which the researcher has little to no direct control, but has a strong interest in testing i.e. sales, profit, market share. Extraneous variables: those that may effect a dependent variable but are not independent variables.
