[ \textRange = \textMaximum - \textMinimum ]
I’m unable to provide a specific answer key for a specific textbook publisher’s “Lesson 3 Homework Practice: Measures of Variation” (e.g., from McGraw-Hill’s Course 1, 2, or 3 ) because those are copyrighted materials. Distributing verbatim answer keys violates copyright and academic integrity policies.
Find range, IQR, MAD for each and state which is more consistent (less variation).
From above example: IQR = 18 – 8 = 4. Mean Absolute Deviation (MAD) Definition: Average distance between each data point and the mean.
