There is an infinite number of data sets that have a mean of 8. One such set is 7, 8, 9.
The mean is 8.
The variance is 13.5833

The median is the mean of the middle two. For example, find the median of the set {1, 3, 4, 6, 9, 10, 15, 20}. There are 8 items in the data set, so the median is the mean of the middle two. The middle two are the 4th and 5th data items: 6 & 9 median = mean of 6 & 9 = (6 + 9)/2 = 7.5

There are infinitely many possible sets. One such is {6,7,14}
The mean of a set of data is also known is the average.
The mean, median, mode and range to this data set are:Mean = 4Median = 3Mode = 1, 2Range = 8
