Question

A sample of 30 Santa Monica College students are asked how many miles they commute to campus."Number of miles commuted' is an example of an:

A- Explanatory

B-Categorical variable

C-Confounding variable

D-Numerical variable

Answer 1

Here number of miles commuted will be a numerical variable. This is because all the 30 students of the sample would have a numerical answer to the question on how many miles they commute to campus.

It is not an explanatory variable because there is no other variable we are interested in comparison of it with whose value this affects. It is not categorical because it takes numerical values. It is not counfounding because again there are no independent dependent scenario here.
