To find: The measures of variability and any outliers for the given set of data.

Answer to Problem 7CR
Range:
Lower quartile:
Median:
Upper quartile:
Interquartile range:
Outliers: No outliers
Explanation of Solution
Given information:
Data set of Claire’s earnings:
Calculation:
Finding range:
Ordering the given data set:
Median:
Lower quartile:
Median of the lower half of the data set,
Upper quartile:
Median of the upper half of the data set,
Interquartile range:
Difference between upper quartile and lower quartile,
Outliers:
Multiply the interquartile range by
Add
Therefore, there are no outliers in the given set of data.
Thus we can find the measures of variability and any other outliers for each set of data.
