Suppose Glenda's rolls were 12,7,3,10,9, 2, 11, 7 and 8. What is the median of Glenda rolls?

What is the mean of Glenda's rolls?

What is the mode? Which would be the best indicator of a typical roll Glenda made, the mean, the median, or the mode?

**MathMate**, Tuesday, March 8, 2011 at 11:57pmMean = total/number of times

So

total=mean*number of times

=6*9=54

Arrange

12,7,3,10,9, 2, 11, 7 and 8.

in ascending order

2 3 7 7 (8) 9 10 11 12

The median is the number which has the same number of numbers higher as lower. In this case, 8 is the middle number, or the median.

In this case, the distribution is quite even, there is not much difference between the three choices. I prefer the mean, since people tend to calculate the average.
