Consider the sample of n = 20 scores. Notice that they are listed in order from 2.5 to 12.0, but that some of the scores are obscured by ***. The mean, M, of these scores is 8.0.
2.5 *** 4.6 5.1 *** 6.0 *** 6.5 6.6 8.5
8.7 9.6 *** 9.9 10.0 10.3 10.5 *** 11.6 12.0
Suppose you are asked for the sample standard deviation of these scores. Since you don’t have all of them, you cannot calculate it.

O 9.5
O 0.5
O 6.4
O 2.7
