we are working with stem and leaf plots....what is an outlier?

OpenStudy (amistre64):

something that doesnt fit ...

OpenStudy (amistre64):

4, 12,13,13,12,16 4 doesnt fit

I have 42,44,48,47,45,53,50,51,65,62,60,74,70,71,72 Why would 47 be an outlier?

OpenStudy (anonymous):

It does not make sense to me

OpenStudy (anonymous):

an outlier is usually a data element more that 2 1/2 std deviations from the mean ... its a data value that probabliy does not belong

OpenStudy (anonymous):

47 looks like it belongs
