Answer» Mean = (44+38+50+48+62+54+43+96+54+98+42+45+54+62+60) ÷ 15 = 850/15 = 56.67 Median = 38,42,43,44,45,48,50,54,54,54,60,62,62,96,98 Median term = 15+1/2 = 8 Median = 54

21. In Mathematics test given to 15 students, the following marks were obtained44, 38, 50, 48, 62, 54, 43, 96, 54, 98, 42, 45, 54, 62, 60.Find the mean and the median.faurth the diameter of the

Answer»

Mean = (44+38+50+48+62+54+43+96+54+98+42+45+54+62+60) ÷ 15

= 850/15

= 56.67

Median =

38,42,43,44,45,48,50,54,54,54,60,62,62,96,98

Median term = 15+1/2 = 8

Median = 54
