Question

Find the mean of the following
data set.
1,1,2,4,6,7,7,8,9,10,12,13,17,17,18

Answer 1

Explanation:

mean = addition of all the values / number of values

. {there is a more formal way of interpreting this mean formula, but I guess u will remember and understand this one faster}.

so....

Mean = 1+1+2+4+6+7+7+8+9+10+12+13+17+17+18 / 15

Mean = 132/15

Mean = 8.8 or 44/5.

Hope this helps.

Good luck .
