Question

the height (in cm) of 8 students is as follows : 155,165,140,175,164,157,171,164 find the mean and median step by step verification ​

Answer 1

Step-by-step explanation:

mean: sum of digits/ no. of digits

155+165+140+175+164+157+171+164= 1290.

no. of digits= 8

mean- 1290/8 = 161.25

median= n+1 / 2 = 8+1/2 = 9/2 = 4.5th term.

Answer 2

Step-by-step explanation:

Mean=sum of total observations /total observations

Mean=155+165+140+175+164+157+171+164/8

=148.875

Median=(n+1)/2 observation

So

5th term/2

=164/2=82
