Question

in the class the students scored marks as follows. find mean, median, mode. 9, 7, 6, 5, 3, 6, 5, 5, 8, 10​

Answer 1

Step-by-step explanation:

3,5,5,5,6,6,7,8,9,10

mean

= (3+5+5+5+6+6+7+8+9+10) /10

=64/10

= 6.4

median

n=10 (even)

n/2 th and (n/2 + 1 ) th observation

10/2 th and (10/2 + 1 ) th observation

5 th and 6th observation

median = (5th + 6th observations)/2

= ( 6 + 6 ) / 2

= 12/2

= 6

mode = 5
