Question

Given the data 14, 26, 23, 19, 24, 46, 15, 21:
What is the outlier in the data?
What is the mean with the outlier?
What is the mean without the outlier?
A. 14; 20.3; 23.5
B. 14; 23.5; 20.3
C. 46; 20.3; 23.5
D. 46; 23.5; 20.3

Answer 1

The outlier in the data is 46.

To find the mean with the outlier, we add all the numbers and divide by the total number of values: (14+26+23+19+24+46+15+21)/8 = 23.5

To find the mean without the outlier, we first need to remove it from the dataset: 14, 26, 23, 19, 24, 15, 21
Then we add those numbers and divide by the total number of values: (14+26+23+19+24+15+21)/7 = 20.3

Therefore, the answer is B. 14; 23.5; 20.3
