Question
Consider these five data values:
10, 14, 15, 16, 20
The mean is 15.0 and the Standard Deviation is 3.6.
Now look at these values: 10, 11, 15, 19, 20. With out doing any calculations what will happen to the standard deviation even
though the mean is still the same.
Select one:
a. The SD will be larger because 11 and 19 are father from the mean than 14 and 16 were.
O b.
The SD will be larger because the new values are close to each other.
O c.
The SD will be smaller because the new values effect the range.
O d. The SD will be smaller because 11 and 19 are farther from the mean than 14 and 16 were.
