How do I get the mean, median and mode?

Hey diddle diddle,

the median's the middle,

you add and divide for the mean,

the mode is the one you see the most and

the range is inbetween  :))

It should ALL be in your textbook!!:

 

Mean [5+7+11+17+8+13+23+15+27] = 126, if you count them, you should get 9

126/9 =14 is the Mean.

 

Find the median of the list:
(5, 7, 11, 17, 8, 13, 23, 15, 27)

The list, sorted from smallest to largest, is:
(5, 7, 8, 11, 13, 15, 17, 23, 27)

The median of the list (5, 7, 8, 11, 13, 15, 17, 23, 27) is the element in the middle, which is:
Answer: |13

 

Find the mode (commonest element) of the list:
(5, 7, 11, 17, 8, 13, 23, 15, 27)

The modes of (5, 7, 11, 17, 8, 13, 23, 15, 27) are:
Answer: |(5, 7, 8, 11, 13, 15, 17, 23, 27)
