Course Description
How can we measure something like “brand loyalty?” It’s an obvious concept of interest to marketers, but we can’t quite take a ruler to it. Instead, we can design and analyze a survey to indirectly measure such a so-called “latent construct.” In this course, you’ll learn how to design and analyze a marketing survey to describe and even predict customers’ behavior based on how they rate items on “a scale of 1 to 5.” You’ll wrangle survey data, conduct exploratory & confirmatory factor analyses, and conduct various survey diagnostics such as checking for reliability and validity.

Preparing to analyze survey data
FreeIn this chapter we will explore the use of surveys in marketing research and the importance of reliability and validity in measurement. We will begin the scale development process and perform exploratory data analysis on freshly-collected survey data.

Exploratory factor analysis & survey development
Now that we have cleaned and summarized our survey results, we will look for hidden patterns in the data using exploratory factor analysis. These patterns form the basis of developing “factors” of an unobserved or latent variable. Of particular interest in this stage of survey development is internal reliability, or whether similar items in the survey produce similar scores.

Confirmatory factor analysis & construct validation
Does the data as collected agree with prior beliefs about the latent variable of interest? In this chapter, we will use confirmatory factor analysis to formally test the hypothesis that our model fits our data. We can now answer the question of construct validity, or: “are we really measuring what we are claiming to measure?”

Criterion validity & replication
In this chapter we will use our newly validated scale to test its relationship to demographic variables like age or spending habits. We will also confirm the reproducibility and replicability of the survey. Finally, we will explore the power of factor scores in modeling customer behavior.
