Question

Find the median of the following uale
5. Find the mean, median and nfode of the following marks of 15 students on a
screening test (out of 20): 2,5, 3,3,0, 18, 5, 7, 11, 15, 1, 13, 0,8,0​

Answer 1

Answer:

2,5, 3,3,0, 18, 5, 7, 11, 15, 1, 13, 0,8,0

Mean of the data = Sum of observations/No of observations

→ 2+5+3+0+ 18+ 5+7+ 11+ 15+1+13+ 0+8+0

15

→88/15 = 5.86

Median of the data= (n+1)/2= (15+1)/2=16/2=8

=8th value of the data that is 11

Mode of the data=

firstly arrange the above data in ascending order

0,0,0,1,2,3,3,5,5,7,8,11,13,15,18

So,the mode =3
