OpenStudy (reemii):
The definition of outlier has something to do with IQR ("InterQuartileRange"). Do you remember?
OpenStudy (shaik0124):
i don't know about outlier but ("InterQuartileRange") is q3-q1
OpenStudy (reemii):
q3-q1 = 57 - 41 = 16 = IQR An outlier is a number smaller than 41 - 1.5 IQR or greater than 57+1.5IQR. that is, smaller than 41 - 24 or greater than 57 + 24
