Descriptive Statistics

First, determine n, which is the number of data values. Second, calculate the arithmetic mean, which is the sum of scores divided by n. For this example, the mean = (8+25+7+5+8+3+10+12+9) / 9 or 9.67. Then, subtract the mean from each individual score to find the individual deviations. Then, square the individual deviations.
