Question

a teacher records unit test scores for all of the students in her class. use the drop-down menus to select the words that make each statement true. the range, mean, median, mean absolute deviation represents the middle of the scores, and it drop - down a measure of statistical variability. the range, mean, median, mean absolute deviation shows how far each score is from the average class score, and it drop - down a measure of statistical variability.

Explanation:

Step1: Analyze the first statement

The first blank needs a measure that represents the middle of the scores. The median is the middle value when data is ordered, so we choose "median". Then, the median is a measure of central tendency, not variability, so the second part is "is not".

Step2: Analyze the second statement

The second blank needs a measure that shows how far each score is from the average (mean). Mean absolute deviation (MAD) calculates the average distance from the mean. MAD is a measure of statistical variability, so we choose "mean absolute deviation" and "is".

Answer:

First statement: median, is not
Second statement: mean absolute deviation, is
