Calculate the standard deviation of the data set. Hint: 95% is two standard deviations on either side of the mean. The standard score, or z-score, is the number of standard deviations from the mean. For example, say a video game player from the convention is 88.75 inches tall. By subtracting the mean, then dividing by the standard deviation, you can determine how many standard deviations this height is from the mean.

Find how many standard deviations 88.75 inches is from the mean. Hint: Subtract the mean from this value, then divide by the standard deviation value.
