Question

A researcher conducted an experiment finding that students that practiced reading at least 10 hours per week had better reading comprehension scores than those that practiced in the two categories: 0 hours and 5 hours. Identify which variable is the IV (AND ***be sure to also include each level of the IV**)

Answer 1

The amount of time a student spent studying for an exam is a quantitative variable because it can be expressed numerically such as 4 hours, and 80 minutes, among other units of time measurement.

Any variable where the data indicate amounts is referred to be a quantitative variable (e.g. height, weight, or age). Any variable where the data represent groupings is referred to as a categorical variable. This comprises categories (like were people placed in a race), rankings (like cereal brands), and binary results (e.g. coin flips).

Variables assessed on a numeric scale are known as quantitative variables, as was covered in the chapter's section on variables. Examples of quantitative variables are height, weight, reaction time, subjective pain rating, temperature, and exam score.
