Consider these six data values: 2, 4, 5, 11, 13, 15. Now look at the data set: 82, 84, 85, 91, 93, 95. Without doing any calculations, explain why the standard deviation will be the same even though the mean is obviously different.
The standard deviation will remain the same because the values in the second data set are the same distances away from their mean as the values in the first set.
The standard deviation will remain the same because the distribution of the second set of values is symmetrical.
The standard deviation will remain the same because adjusting values within a data set only affects the center of that data set, not its spread.
The standard deviation will remain the same because adjusting values within a data set only affects the shape of that data set, not its spread.
