Median would be the 4th term and the 5th term's average

|dw:1396677557471:dw| it is 85.

OpenStudy (anonymous):

mode is \[51+75+79+81+ 89+90+96+98=659 \]

659/8=82.37

OpenStudy (anonymous):

put the numbers in least to greatest and see the middle one.

OpenStudy (anonymous):

but the mode is the most. so it is no mode. so it is C

OpenStudy (kc_kennylau):

mode is not 82.37, mean is 82.37
