Question

leveled practice in 7 and 8, complete each statement. 7. use the stem - and - leaf plot. a. the data set is evenly distributed, so the appropriate measure of variability is the. b. the data set has no outliers, so the appropriate measure of center is the. number of fish in a fish tank 0|9 9 1|1 2 5 5 6 6 7 7 7 7 8 2|0 4 1 key 0|9 = 9 fish

Explanation:

a. For evenly distributed data, the standard deviation (or interquartile range, but standard deviation is the most common measure for symmetric/even distributions) is the appropriate variability measure as it accounts for all data points.
b. When a data set has no outliers, the mean is the appropriate measure of center because it uses all values in the data set and is reliable for symmetric, outlier-free data.

Answer:

a. standard deviation (or interquartile range)
b. mean
