Answer 17

we know now @mayankdevnani

Answer 18

so can you solve it ?

Answer 19

Mean deviation is distance from middle value correct?

Answer 20

it is median

Answer 21

Yea i now it B

Answer 22

Good !

Answer 23

I thought mean deviation is like, find the mean, then take all the distances from that mean from the other values and add together and then divide by the amount of numbers?

Answer 24

Median is simply the middle value of the entire set of data.

Answer 25

My bad, it's not standard deviation, it's much simpler.
