Answer:
below :)
Step-by-step 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.
