Refer to Exercises 3.14 and 3.15. Compute a 10% trimmed mean for both data sets. Do the extreme values affect the 10% trimmed mean? is a 5% trimmed mean affected?
Exercise 3.14
Compute the mean, median, and mode for the following data:
11 | 17 | 18 | 10 | 22 | 23 | 15 | 17 |
14 | 14 | 10 | 12 | 18 | 18 | 11 | 14 |
Exercise 3.15
Refer to the data in Exercise 3.14. Replace the measurements 22 and 23 with 42 and 43. Re-compute the mean, median, and mode. Discuss the impact of these extreme measurements on the three measures of central tendency.
