4,10,1,7,1,8,1,5,2
The mean represents the average or the sum of the data divided by the number of pieces of data :
mean+=+%284%2B10%2B1%2B7%2B1%2B8%2B1%2B5%2B2%29%2F9+=+4.33
The median is the value in the middle of a set of ranked data:
1,1,1,2,4,5,7,8,10
median+=+4
The mode is the piece of date that occurs most frequently.
mode+=+1

The midrange is the value half way between the lowest and highest
values in a set of data. It is found by adding the loweast and highest values and dividing the sum by 2.
midrange+=+%281%2B10%29%2F2+=+11%2F2=5.5
