The table represents the scores of ten students in Ms. Williams’s class on a math and science test. Which statement correctly compares the two sets of data?

• The mean score in Math is greater than the mean score in Science.

• The interquartile range of Math scores is greater than the interquartile range of Science scores.

• The scores in Math are more consistent than the scores in Science.

• The range of Science scores is greater than the range of Math scores.

Miss Jackson is comparing her students' scores on the science test to the scores on the math test. She has recorded the scores for each test on the dot plots. Which of the following statements is true about the data?

• The mean absolute deviation of the math scores is greater than that of the science scores; therefore, the math scores are higher than the science scores.

• The mean absolute deviation of the science scores is greater than that of the math scores; therefore, the science scores are higher than the math scores.

• The mean absolute deviation of the science scores is greater than that of the math scores; therefore, the science scores are more spread out than are the math scores.

• The mean absolute deviation of the math scores is greater than that of the science scores; therefore, the math scores are more spread out than are the science scores.

Coach Keller is comparing the heights of the students on the basketball and volleyball teams. The line plots below show the heights, in inches, of the students on each team.

• The basketball team's heights has a greater interquartile range than the volleyball team's heights.

• The volleyball team has a smaller range of heights than the basketball team.

• The mean absolute deviation of the basketball team's heights is greater than the mean absolute deviation of the volleyball team's height.
