The standard deviation will decrease when the outlier is removed. Standard deviation represents the spread of data from the mean. Removing a highvalue outlier decreases the spread of data from the mean. Removing a lowvalue outlier decreases the spread of data from the mean. In both cases the standard deviation decreases.

First of all, to calculate the standard deviation of these scores you would need to calculate the mean of those scores. The sum of the raw scores divided by the total number of scores. For example: 5 + 6 + 9 + 2 + 8 = 30. 30 / 5 = 6. So our mean score is 6.
