Question

The chess club at a school has 15 members. The number of games won in tournament play this season by each member is listed.

6, 6, 6, 7, 10, 11, 12, 13, 14, 14, 15, 16, 18, 18, 30
What measure is most appropriate for describing variability in this data distribution?

Answer 1

The most appropriate measure for describing variability in this data distribution is the range. The range provides a measure of how spread out the data is.

Step-by-step explanation:

The most appropriate measure for describing variability in this data distribution is the range.

The range is calculated by subtracting the lowest value from the highest value in the data set. In this case, the lowest value is 6 and the highest value is 30, so the range is 30 - 6 = 24.

The range provides a measure of how spread out the data is. In this case, the range is relatively large, indicating a wide variability in the number of games won by the chess club members.
