Question

The mark of 20 students are given below -
12,0,5,6,8,10,10,5,12,20,20,1,2,5,10 find the mean median mode of marks​

Answer 1

Answer:

mean=given number/total number

12+0+5+6+8+10+10+5+12+20+20+1+2+5+10/15

mean=9.06

meadian= arrange in ascending order

0,1,2,5,5,5,6,8,10,10,10,12,12,20,20

meadian=n+1/2

=(15+1/2)th observation

meadian=8th observation=>8

mode= frequently occurring number is 5 and 10

hope it's helpful....
