so how does your course define outliers?

OpenStudy (brandonw998):

In my book it says "Outliers are points that don't fit the pattern of the rest of the data"

OpenStudy (amistre64):

thats the def i was raised with ... these days they have some formula like: mean +- IQR(1.5) defines the interval that is NOT ourliers

OpenStudy (amistre64):

OpenStudy (amistre64):

or something like that

OpenStudy (amistre64):

what is q3 - q1?

OpenStudy (brandonw998):

So the outlier is 30.052?

OpenStudy (brandonw998):

Q3-Q1=6

OpenStudy (amistre64):

and 6*1.5 is 9 so by one definition, an outlier is any value that is NOT between q1-9, and q3+9

OpenStudy (amistre64):

no numbers are less than 8.1 any on the high side?

OpenStudy (brandonw998):

So 33.2 and 34 are outliers?

OpenStudy (brandonw998):

So the answer is D?

OpenStudy (amistre64):

if we accept the definition using the IQR yes. so our box plot should have 2 little open dots on the high side

OpenStudy (amistre64):

D would be my best educated guess as well

OpenStudy (brandonw998):

Thank you so much!

OpenStudy (amistre64):

good luck :)
