To determine which letter appears the most often in her favorite poem, Ashley should use the mode. The mode is the value that occurs with the highest frequency, making it perfect for identifying which letter is the reigning champ in her poetic masterpiece! Regarding the salaries of the 9 employees, using the median would be the best measure to summarize the data. The median provides a better representation of the central tendency when there may be outliers, as it positions itself right in the middle of the sorted salaries, helping illustrate the typical employee wage more accurately than the mean. When analyzing the last 9 calls to a customer support line, the median is again the ideal choice for summarizing the data. Given the relatively small and consistent range of call lengths, the median captures the point at which half of the calls are shorter and half are longer, providing a clearer picture of the typical call duration without being swayed by any potential outliers.
