Question

Jasper is using the following data samples to make a claim about the house values in his neighborhood:


House Value
A $150,000
B $175,000
C $200,000
D $167,000
E $2,500,000


Based on the data, should Jasper use the mean or the median to make an inference about the house values in his neighborhood?
He should use the mean because it is in the center of the data.
He should use the median because it is in the center of the data.He should use the median because there is an outlier that affects the mean.
He should use the mean because there are no outliers that affect the mean.

Answer 3

Well first, lets differentiate what the mean is and what median is.

Answer 4

okay

Answer 5

Mean is the average, where median is the measurement, where the data is arranged from lowest to highest, but when you have a bunch of data, and you set it up from lowest to highest the middle number is the median.

Answer 6

638400 is the mean

Answer 7

right?

Answer 8

I haven't done the calculation but I believe you, so do you think it's wise to use median or mean for this?

Answer 9

Well for average you add up all the numbers and divide by the amount of numbers given.

Answer 10

yeah that's what i did

Answer 11

the median would be house c which is 200,000

Answer 12

Not quite

Answer 13

cause it's the middle number right?

Answer 14

Remember you have to arrange them lowest to highest :)

Answer 15

oh yeah damn

Answer 16

You're getting it though, it's good!

Answer 17

then it would be B

Answer 18

right?

Answer 19

Well this is not my expertise, but first lets eliminate a few options.

Answer 20

okay what d we do first

Answer 21

Given the definition of what I said above what can we eliminate?

Answer 22

We should be able to eliminate 2 options

Answer 23

i think we should be able to eliminate the mean because it is not the center of the data

Answer 24

and if we eliminate that then we should be able to eliminate this one : He should use the mean because there are no outliers that affect the mean.

Answer 25

is this correct isthere a way to find out?

Answer 26

There's a catch to this question, and I think you got it, because if we use mean we would get a weird answer right? Due to the high number of the last house, so yes you seem to be correct, we can say B!

Answer 27

okay thanks for the help i have one more question i need help with are u able to help me?

Answer 28

Well actually it could be C

Answer 29

Lets just eliminate A and D because we know it's not the mean.

Answer 30

ok

Answer 31

And B doesn't seem to be specific enough

Answer 32

that's true

Answer 33

Mhm, I think it could be C, I'm sorry man, I haven't dealt with mean/ median and such in a long time haha.

Answer 34

but for c is there an outlier that affects the mean?

Answer 35

ha me either

Answer 36

Yeah I think they mean the last house, look how expensive it is, that would be the outlier right, and that would screw up the mean.

Answer 37

yeah that's true

Answer 38

so then it's c right?

Answer 39

I would say so, lets hope for the best!

Answer 40

ok can you help me with one more

Answer 41

Well I was just about to go, unless it's a quick one :p
