How do you find range mode median and mean?

Answer 1

Range is the biggest number minus the smallest number in a series.

ex. 21, 35, 2, 2, 18, 1, 56 56-2=54

Median is the middle number in a series. First arrange the numbers from smallest to largest. If there are an even number of numbers in the series, the median is the average (mean) of the two middle numbers.

ex. 1, 2, 2, 18, 21 ,35, 56 18

Mode is the most repeated number in a series. It appears the most times. There can sometimes be more than one mode. If no number appears more than once, then there is no mode.

ex. 1, 2, 2, 18, 21, 35, 56 2

To find the mean, add up all the numbers and divide by the number of numbers.

ex. 1, 2, 5, 9, 3 1+2+5+9+3=20 20/5=3
