Question

Which of the following is not a bivariate data?

A. Study a group of college students to find out their height and their weight

B. Study a group of diabetic patients to find their weights

C. Study a group of college students to find out their average SAT score and their age

D. Study a group of college students to find out their average standardized admission test (SAT)

Answer 1

First, we need to understand the difference between bivariate and bivariable (mistakenly used simultaneously). If we are using two variables and cross tabulating them or pairing them then it is a bivariable analysis. If we we are predicting two outcomes then it is a bivariate analysis (repeated measures with two outcomes). Similar concept is applied to multivariable and multivariate. So, if the question means "not bivariable", then B, and D are correct. Given that the researcher will pair weight and height for each individual for a certain purpose (e.g., to see the correlation or association)
