Document Summary

Statistical measure that attempts to determine the single value that is most typical/representative of the entire set of scores. Midpoint of the list of scores in a distribution that are ordered smallest to largest. The score/category that has the greatest frequency. The sum of the scores divided by the number of scores. A sample of n = 12 scores has a mean of m = 8. The value of x for this sample is 48 because 12( n ) x 8( m ) = 96. A sample of n = 7 scores has a mean of 5. The value of x before being doubled for this sample is 35 because 7( n ) x 5( m ) = 96. The value of x a fter being doubled for this sample is 140. A distribution scores show mean = 31 and median = 43.
