4 0

Answer: 120

Step-by-step explanation:

The median of a given set for numbers will be gotten when we arrange the numbers that are given in either ascending or descending order and then get the number in the middle.

Therefore, since we are given 90,100,120,120,140, it means that we have 5 numbers and the 3rd number will be the median distance. Thus will be: = 120

"if the standard deviation of a group of 20 scores is 15, what is the variance?"

DerKrebs [107]

We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.

Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.

$\text{ Variance}=\sigma^{2}\\
=15^{2}=225$

Therefore, our variance is 225.
