Which value is the difference between the MEAN and MEDIAN for this data set?

45.5, 35.6, 26.8, 41.8, 51.4, 71.9

A)

0.95

B)

1.35

C)

1.85

D)

2.15

The answer is 1.85
List in ascending order: 26.8, 35.6, 41.8, 45.5, 51.4, 71.9
Find the median:
41.8 + 45.5
2
= 43.65. Find the mean:
26.8 + 35.6 + 41.8 + 45.5 + 51.4 + 71.9
6
=
273
6
= 45.5
45.5 − 43.65 = 1.85

1.85

Step-by-step explanation:

Firstly we will have to calculate the mean and the mean is the sum of the numbers divided by the number

Mean=45.5+35.6+26.8+41.8+51.4+71.9/6

Mean=273/6

Mean=45.5

Median means the middle number

So we will have to rearrange the numbers

26.8,35.6,41.8,45.5,51.4,71.9

So the middle numbers will be 41.8 and 45.5

Median=41.8+45.5/2

=87.3/2

=43.65

So the difference between the mean and median

45.5-43.65

1.85

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
