Research, copy, and paste a data set table related to your field of study that has more than three elements and three variables. How many elements are in the data set? How many variables are in the data set? Identify which variables are categorical (qualitative) or numerical (quantitative). What type of measurement scale is used for each of the variables? Please reference your source. Note: Even among experts, there is often spirited discussion regarding how to determine the appropriate measurement scale. (Refer to Chapter 1 Review: Supplementary Exercises 2 in the textbook.)
