Introduction to Survey Methodology: Sampling and Factor Analysis



What is this course about?

Where information or data is not available, primary data collection often is needed. As much as the ideal case is to collect information or data from the entire population, at times this becomes an impossible feat due to its massiveness. That is why sampling is required and to ensure the data remains robust and representative of the larger population, unbiased sampling techniques are often performed. Furthermore, where data gathering involves surveys, the methodology and approach is often imperative to the representativeness of the population behavior. One of the ways to test the reliability and construct of a surveys is to perform a factor analysis, of which has been used widely in social research in terms of behavioral sciences and psychological studies in terms of psychometrics.

In this course, participants will not only learn the importance and types of unbiased sampling techniques and survey methodologies, factor analysis in terms of validating the reliability of the constructs of a survey will also be covered.

Suitable For
