Question:

This week spend time discussing the similarities and differences between correlation and regression, and why one would use correlation instead of regression. Consider how often there are bivariate relationships and whether a bivariate relationship will be meaningful for your DBA doctoral study as compared to a regression, which examines relationships differently.

As a researcher, you will become familiar and comfortable with the measures and scales others in choose to measure data. Understanding study measurement methods can help clarify how you might employ these measurement instruments. In this Discussion, you will find an example of a test and a scale used in your discipline's literature, analyze its use in the study, and analyze the relationships among these instruments, populations, and the concepts of reliability and validity.
