OpenStudy (ivettef365):
yest the median is correct
OpenStudy (ivettef365):
no to find the first quartile Q1, you divide the data in two parts, so you have the following:
2,2,3,4,5 and 8,8,9,10,15
OpenStudy (ivettef365):
find the median of the first half that is Q1
find the median of the second half that is Q3
OpenStudy (pphalke):

OpenStudy (ivettef365):
what is the median of 2,2,3,4, 5
