The table shows the test scores of students who studied for a test as a group (group a) and students who studied individually (group b). which would be the best measures of center and variation to use to compare the data? the scores of group b are skewed right, so the mean and range are the best measures for comparison. both distributions are nearly symmetric, so the mean and the standard deviation are the best measures for comparison. both distributions are nearly symmetric, so the median and the interquartile range are the best measures for comparison. the scores of both groups are skewed, so the median and standard deviation are the best measures for comparison.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
