Answer 1

The mean is found by adding up the "n" numbers and dividing the total by "n"

The median is found by re-arranging the "n" numbers in ascending order, then computing (n+1)/2. If that number is an integer k, then the median is the kth number. If that number is between integers k and k+1, then the median is the average of the kth and k+1st numbers.

The mode is the most often occurring number(s), that occurs more than once. If no number occurs more than once then there is no mode.
