Question

the great lakes contain more than 20% of the worlds freshwater. the maximum depth of the 5 lakes ranges from 210 feet for lake erie to 1,333 feet for lake superior. the mean of the maximum depths is 804 feet, and the mean absolute deviation is 260 feet. which is a measure of how much the maximum depths of the great lakes vary? 210 feet 260 feet 804 feet 1,333 feet

Explanation:

Step1: Recall the concept of mean - absolute deviation

The mean - absolute deviation (MAD) is a measure of the average distance between each data value and the mean. It tells us how much the data values vary from the mean.

Step2: Identify the measure of variation

We are asked for a measure of how much the maximum depths of the Great Lakes vary. The mean absolute deviation given as 260 feet is the measure of this variation.

Answer:

260 feet
