1, 3, 2, 2, 1, 3, 3, 1

Part A: What is the mean of the data? Show your work. (4 points)

Part B: Use your answer from Part A to calculate the mean absolute deviation for the data. Show your work. (6 points)

Answer 1

I already finished part A

Answer 2

Answer 8

first step:
the requested mean "m" is given by the subsequent computation:
\[\Large m = \frac{{1 + 3 + 2 + 2 + 1 + 3 + 3 + 1}}{8} = ...\]

Answer 9

16/8= 2

Answer 10

correct!

Answer 11

second step:

Answer 12

for each value v, you have to compute the difference:
v-2 and take the result without the sign

Answer 13

namely, for example:
1-2= -1, so you take 1
3-2= 1, so you take 1
please continue

Answer 14

1-2+3-2+2-2+2-2+1-2+3-2+3-2+1-2
so 1,1,0,0,1,1,1,1

Answer 15

6

Answer 16

6/8

Answer 17

the sum of the absolute deviations is
1+1+1+1+1+1=6 correct
and the requested mean is:
6/8=...?

Answer 18

since we have 8 entries

Answer 19

erm 1.2?

Answer 20

6/8=3/4=...?

Answer 21

0.75

Answer 22

correct!
