## Homework Statement

Suppose that I have the following groups/categories with how each is measured next to them:

Response to light – measured on a scale of 1 to 4

HDL levels – continuous value from 1 to 100

Smoker status - smoker or non-smoker

The question is as follows:

What are the highest-level measures of central tendency and variability that can be used?

## Homework Equations

If descriptive, equations would not apply.

## The Attempt at a Solution

I know that central tendency includes mean, mode, and median and variability includes variance and standard deviation, but could someone please tell me what is meant by “highest-level measures”? Do I include the descriptive term (for example, central tendency answer "mean") or an actual measurement?

Thank you.
