Question

multiple choice question
which one of the following is not a characteristic of a frequency distribution?
it uses collectively exhaustive classes.
it summarizes qualitative data.
it displays the number of observations in each class.
it uses mutually exclusive classes.

Explanation:

A frequency distribution organizes data (both quantitative and qualitative) into classes that are mutually exclusive (no overlap) and collectively exhaustive (all data fits), showing the count of observations per class. The claim that it only summarizes qualitative data is incorrect, as it also summarizes quantitative data.

Answer:

It summarizes qualitative data.
