Compare Analyze Data

Given the data set below:
15, 56, 58, 60, 63, 75, 80, 80, 85
How does the outlier affect the distribution of the data?

• The outlier skews the distribution to the left.

• The outlier skews the distribution to the right.

• The outlier makes the distribution more symmetrical.

• The outlier has no effect on the distribution.

Mr. Burns created a box plot, consisting of scores from 0 to 100, to compare quiz scores from his first and second period science classes.

• The lowest score from both classes came from the second period class.

• The first period class had the greater median score.

• The first period class had the greater range of quiz scores.

• The second period class had the greater variability of quiz scores.

Given the two box plots, what statements are true? Select all that apply.

• The two plots have the same range.

• The spread of the middle half of Set A's data is less than that of Set B.

• Set A's median is greater than Set B's median.

• Set A's mean is greater than Set B's mean.
