Question

Compute Mean, Median and Mode for the following data

Class 0-10 10-20 20-30 30-40 40-50

Frequency 3 5 9 3 2​

Answer 1

Answer:

Class:- Frequency(f):- x:- f(x):-

0-10 3 5 3×5=15

10-20 5 15 5×15=75

20-30 9 25 9×25=225

30-40 3 35 3×35=105

40-50 2 45 2×45=90

Total:- €f=22 €f(x)=510

Mean=€f(x)/€f.

=510/22.

=23.18181818181.

Median=n+1/2.

=5+1/2.

=6/2.

=3.

So, Median of 3rd value=9.

(or).

In ascending order, 2,3,3,5,9.

So, Median of 3rd value=3.

Mode=3.

The symbol is not correct.

I think this is your answer.
