First, we have to arrange data in ascending order.
After arranging our data becomes,
`39,40,40,41,42,46,48,52,52,52,54,60,62,96,98`
`Mean = `Sum of all observations`/`Total number of observations
`Mean = (39+40+40+41+42+46+48+52+52+52+54+60+62+96+98)/15 = 822/15 = 54.8`
Median can be obtained by finding the middle term.
Here, Middle term is `8^(th)` term.
