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
