Question

A researcher decides to determine if the type of writing utensil that a student uses while doing their math affects their accuracy. A group of 1200 high school students in Algebra are randomly divided into four groups. One group uses a regular pencil, another uses a mechanical pencil, one group uses a pen and the fourth group is allowed to use whatever type of utensil they feel like. A math test is given and the results are tabulated for accuracy. The variable- type of writing utensil - is what type of variable?

Answer 1

Since the variable type of writing utensil assumes labels and not numbers, it is classified as qualitative.

What are qualitative and quantitative variables?

• Qualitative variables: Assumes labels or ranks.

• Quantitative variables: Assume numerical values.

In this problem, the type of writing utensil has 4 labels: regular pencil, mechanical pencil, pen, whatever.

Hence, since the variable assumes labels and not numbers, it is classified as qualitative.
