How do you calculate the mean, median, and mode of 7, 3, 2, 1, 13, 8, 1, 5, 14, 11, 15?
Mean: the average of your numbers ie sum of your numbers divided by the number of your numbers
Median: the middle value of all your numbers when placed in ascending order
Since there are 11 numbers, your median will be your 6th number which is 7
Mode: the number that occurs the most
SO: from above when the numbers are ordered in ascending order, you'll noticed that 1 occurs twice. Hence, your mode is 1
By arranging the series
Order your results (from the lowest observation the to greatest):
The mean is
The median is 7 (it disects the set - it is the 6th number).
The mode is 1 (there are two 1s repeated). Only one mode exists in this series.
