Question

Find the mean of 12,8,7,10,8,8,10

A.63
B.12.6
C.9
D.7

Answer 1

It'd be C. To find mean, you first add all the terms, than divide by how many terms there were. 12+8+7+10+8+8+10=63, and there are 7 terms, so 63÷7=9.

Answer 2

mean = 9 → C

mean =
`(sum of data)/(count)`

=
`(12 + 8 + 7 + 10 +8 + 8 + 10)/(7)` = 9
