Question 1

Find the standard deviation for each of the data sets
A: \(4,5,5,7,8,9 \)
B: \(4,5,5,7,8,20\)
In comparing the standard deviations what effect does the outlier in data set \(B\) have on the standard deviation?
A: SD = 2.00, B: SD = 5.98; the outlier increases the standard deviation
Correct
A: SD = 2.00, B: SD = 2.00; the outlier has no effect
A: SD = 5.98, B: SD = 2.00; the outlier decreases the standard deviation
A: SD = 2.00, B: SD = 3.50; the outlier slightly increases the standard deviation
