In 2007 the average SAT scores for colleges were posted on the web. Here are some of those scores. Calculate the mean, median and mode for these SAT scores.

To find the mean, find the sum and divide by the number of scores.

Mean = 1910

To find the median, sort the scores from least to greatest. Calculate the middle value. There are 20 scores, so we find the average between the 10th and 11th scores.

Median = 1922.5

The mode is the number that occurs most frequently. Three numbers occur twice in this set of numbers. The mode is all three of these numbers.

Mode = 1960, 1775, 1795
