which measure should be used to summarize the data?
mean median mode

Explanation:

• (a) The mode is the value that appears most frequently. Since Pablo wants to find the letter that appears most often, the mode is the appropriate measure.
• (b) When there are no extreme values and the data is relatively symmetric, the mean can be a good measure. Here, the salaries don't have extreme outliers that would skew the mean.
• (c) The data set has an outlier (62). The median is less affected by outliers compared to the mean. The mode is not suitable as there are no repeated values.

Answer:

(a) Mode
(b) Mean
(c) Median
