Question

find mean, median of 1st ten multiple of 8

Answer 1

Mean = sum of all observations /total no of observations
= 8+16+24+32+40+48+56+64+80/10
= 368/10
=36.8
Median
Since n=10 ( even)
So median =
$\frac{n}{2} + \frac{n}{2} + 1$=10/2 +10/2 +1
=5th observation + 6 observation
=40+48
=88/2
=44
Hence, mean is 36.8 & median is 44.
Hope it help.
