look at the given dot plot
do you see any outlier ?

- tatumnolan

Yes

- tatumnolan

The dot on 10

- ganeshie8

Exactly, since an outlier is there, "median" is the best measure for center
median is robust to outliers as the outliers don't affect median at all.

- tatumnolan

ok so it would be median?

- ganeshie8

Yes

- tatumnolan

ok

- tatumnolan

Ill post again if I need help on another question

- tatumnolan

I Dont understand this subject its very odd for me

- tatumnolan

Im sorry I feel like its c based on the last

- tatumnolan

but im not sure

- ganeshie8

do you see any outliers here ?

- tatumnolan

Yes 2

- ganeshie8

so use "inter quartile range" for spread

- tatumnolan

Would it be Median again?

- tatumnolan

oh

- ganeshie8

"median", "mean" measure "center
"mean absolute deviation". "interquartile range" measure variability

- tatumnolan

Ugh Im so confused

- ganeshie8

when you have outliers, use below :
1) median for center
2) interquartile range for variability

- tatumnolan

ok

- tatumnolan

THanks

- tatumnolan

mean absolute deviation right?

- ganeshie8

since you have outliers in the given bar chart, you would use "inter quartile range"

- tatumnolan

I got confused and Put in interquartile range

- tatumnolan

I got it wrong but right the second time

- tatumnolan

sorry :/

- ganeshie8

thats okay

- tatumnolan

so can you give me a Definition for dummy's of mean absolute deviation

- tatumnolan

?

- ganeshie8

mean absolute deviation
as the name says, it sees how much far away each data value is located from the "mean"

- tatumnolan

ok

- tatumnolan

Thanks

- tatumnolan

or is there something else

- ganeshie8

first find the mean

- tatumnolan

ok

- tatumnolan

is the mean 160?

- ganeshie8

Correct

- tatumnolan

Ok

- tatumnolan

Next step?

- ganeshie8

see how much far away each of the data point in given table from the mean

- ganeshie8

simply subtract each of the given data point from the mean

- tatumnolan

im confused

- tatumnolan

what am I subtracting from 160?

- ganeshie8

|dw:1440210090036:dw|

- tatumnolan

39?

- ganeshie8

Yes, find that for each row in the table

- tatumnolan

oh boy

- tatumnolan

ok

- tatumnolan

and then what?

- ganeshie8

|dw:1440210261023:dw|

- ganeshie8

first do that,
rest is easy il walk you through
