Mathematics

In Mathematics we have been learning about the Mean, Median, Mode and Range of a set of numbers.
Mean= The average.
Median=Middle
Mode=Most common.

Can you find the Mean, Median, Mode and Range of the scores recorded below from chocolate sales in Room 11?

Example: 7,8,15,13, 15

Mean:  Step One:  Add all the numbers in the set                Answer: 58
             Step Two:  Divide the total (58) by the number of scores you added up (5) Answer: 11.6
So the Mean of the scores recorded from chocolate sales in Room 11 equals 11.6

Median:  Step One: List the scores in order ( 7,8,13,15,15)
                Step Two: Start counting one off from each end until there is only one number left in the
                                  middle (13)
So the median of the scores recorded from chocolate sales in Room 11 equals 13

Mode:  Step One:   List the scores in order ( 7,8,13,15,15)
             Step Two:   Find the number/ scores that is the most common (15) Note: Sometimes there
                                  is more than one mode or no mode at all.
So the Mode of the scores recorded from chocolate sales in Room 11 equals (15)

 

1) 6,8,13,15,18,22,25                           2) 7,11,18,13,8,32,14                              3) 6,13,2,11,9,6,3,2,15

4) 14.1,12.9, 11.9, 19.1                        5) 142, 117,137,116,124,139
