Variable of Interest

This is the specific element being measured or observed in a study. In this case, it refers to the annual advertising revenue of Facebook, which is the focus of the analysis.

Data types are classifications that describe the attributes of data. Here, the data are quantitative since they involve numerical values representing the amount of revenue.
