Identify the outlier in the following list. then find the mean and median of the list with and without the outlier. 10, 4, 20, 5, 11, 150, 7 a. outlier = 10 mean with outlier = 29.6 median with outlier = 10 mean without outlier = 44.1 median without outlier = 10.5 c. outlier = 150 mean with outlier = 9.5 median with outlier = 8.5 mean without outlier = 29.6 median without outlier = 10 b. outlier = 10 mean with outlier = 10 median with outlier = 29.6 mean without outlier = 8.5 median without outlier = 9.5 d. outlier = 150 mean with outlier = 29.6 median with outlier = 10 mean without outlier = 9.5 median without outlier = 8.5

Ответ:
Mean with outlier: 29.6
Median with outlier: 10
Mean without outlier: 9.5
Median without outlier: 8.5
Ответ:
d. Outlier = 150 Mean with outlier = 29.6 Median with outlier = 10
Mean without outlier = 9.5 Median without outlier = 8.5
Outlier: 150
The value in the data set that is far greater or less than most of the other values in the data set.
Mean w/ Outlier: 29.6
4 + 5 + 7 + 10 + 11 + 20 + 150 = 207
207 / 7 = 29.6
Median w/ Outlier: 10
The 4th value out of the 7 total in the data set, 10; it is the median because it is the middle-most value in the data set.
Mean w/o Outlier: 9.5
4 + 5 + 7 + 10 + 11 + 20 = 57
57 / 6 = 9.5
Median w/o Outlier: 8.5
When there are two middle-most values in a data set, add them together and divide by to ( average them ) to get the median.
7 + 10 = 17
17 / 2 = 8.5
