Mean— A mathematical average of a group of numbers

If the number of observations is even, then the median is the mean of the two middle observations in the ordered list. Example Find the median for the sample of four salaries from Microsoft. First put the salaries in order: $30,000 $32,500 $35,000 $36,000 Median = $33,750. The mode is the value that occurs most frequently in a data set. ................
