Question

How do you calculate the mean, median, and mode of 7, 3, 2, 1, 13, 8, 1, 5, 14, 11, 15?

Answer 1

Below

Explanation:

Mean: the average of your numbers ie sum of your numbers divided by the number of your numbers
SO: `(7+3+2+1+13+8+1+5+14+11+15)/11=80/11=7.27`

Median: the middle value of all your numbers when placed in ascending order
SO: `1,1,2,3,5,7,8,11,13,14,15`
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

Answer 2

By arranging the series

Explanation:

Order your results (from the lowest observation the to greatest):

`1, 1, 2, 3, 5, 7, 8, 11, 13, 14, 15`

The mean is `Ave=(1+1+2+3+5+7+8+11+13+14+15)/11`

`Ave= 80/11=7.28`

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.
