Based on the scale of measurement for each variable listed below, which measure of central tendency is most appropriate for describing the data? a) the time (years) it takes a sample of students to graduate college. b) the blood type (a, b, ab, o) of a group of participants. c) the rankings of college undergraduate academic programs.

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
