Question

The number of pets owned by eight classmates is shown below:

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 just need help with b

Answer 2

I got 2 for the absolute deviation is that correct?

Answer 3

what up

Answer 4

it is 2

Answer 5

so you was correct

Answer 6

can you show me how you know?

Answer 7

what did you get for the mean?

Answer 8

first you add all of the numbers which was 16 and then divide by how many people there was which was 8 so 16 divided by 8 is 2

Answer 9

thats the mean 2

Answer 10

for the part a i got 2

Answer 11

to get the mean absolute deviation you add up the absolute differences of each value from the mean . Add these values then divide by 8

Answer 12

yes

Answer 13

1 2-1 = 1
3 3 -2 = 1
2 2 -2 = 0
2 2 - 2 = 0


and so on

Answer 14

i did this to find the absolute deviation 1-2+3-2+2-2+2-2+1-2+3-2+3-2+1-2

Answer 15

so all that above 8

Answer 16

sure

Answer 17

so 6/8

Answer 18

yes

Answer 19

Hmm to be honest i'm not sure I'll have to check

Answer 20

same im confused im going to go over it again and you tell me how you it so we can compare

Answer 21

*do

Answer 22

right - you take ABSOLUTE values so for instance

first values is 1: 1 - 2 = -1 The absolute value of -1 is 1.

so there are no negatives

Answer 23

so 6/8 is not correct

Answer 24

alright

Answer 25

i was doing something else what

Answer 26

oh hold on it does work out to 6/8

it is 1+ 1 +0+ 0 + 1+ 1+1 + 1 = 6


so 6/8 or 3/4

Answer 27

Yeah

Answer 28

i see

Answer 29

ok

Answer 30

what you wrote
1-2+3-2+2-2+2-2+1-2+3-2+3-2+1-2 = 0
