Exploratory Research Design:Secondary Data

Primary vs. Secondary Data : 

Primary vs. Secondary Data Primary data are originated by a researcher for the specific purpose of addressing the problem at hand. Secondary data are data which have already been collected for purposes other than the problem at hand.

A Comparison of Primary & Secondary Data : 

A Comparison of Primary & Secondary Data Primary Data Secondary Data Collection purpose For the problem at hand For other problems Collection process Very involved Rapid & easy Collection cost High Relatively low Collection time Long Short Table 4.1

Uses of Secondary Data : 

Uses of Secondary Data Identify the problem Better define the problem Develop an approach to the problem Formulate an appropriate research design (for example, by identifying the key variables) Answer certain research questions and test some hypotheses Interpret primary data more insightfully

Criteria for Evaluating Secondary Data : 

Criteria for Evaluating Secondary Data Specifications: Methodology Used to Collect the Data Error: Accuracy of the Data Currency: When the Data Were Collected Objective(s): The Purpose for Which the Data Were Collected Nature: The Content of the Data Dependability: Overall, How Dependable Are the Data
