Question

Example 2: Given below is the raw data of the marks
obtained by 30 students in maths test out of 50.​

Answer 1

:

We know,

Mean=Sum of all observations/Total number of observations

Here, Sum of all observations =10+20+36+92+95+40

+50+56+60+70+92+88+80+70+72+70

+36+40+36+40+92+40+50+50+56+60+70+60+60+88=1779

Total number of observations =30

So, Mean=177930=59.3

Answer 2

Answer:

59.3 is the correct answer
