Answer:

below :)

Explanation:

1. Organize date in order

6,9,10,12,12,13,15,20,42

measure of center = median or mean, so I’ll shall do both

mean:

Add up all of the numbers and divide by the number of numbers in the data set

1) count the amount of #’s there are, which is: 9

2) Add all the numbers together then divide by 9:

6 + 9 + 10 + 12 + 12 + 13 + 15 + 20 + 42/9 = m (median)

139/9 = m

15.4444444444 = m

Hence, the median is 15.4444444444.

median:

The median is the middle value in a list ordered from smallest to largest.

6,9,10,12,12,13,15,20,42

Find number that is in the middle, which is 12.


(Just to do it) mode:

The mode is the most frequently occurring value on the list.

This would be 12, since there is 2 12’s, making it the most occurring value on the list.
