Here is your answer
To find mean we need xi and fi and f where xi = mid number and fi is the frequency and f is the total sum of the frequencies.
Mean = summation (fix) /summation f
Median = l+N/2 -cf/f × h
L = lowest class boundary.
Cf = the cumulative frequency
f = frequency of that class
h = width
Mode = L + f0-f1/2fo-f1-f2
f0 = frequency of the class
f1 = upper freauncy
f2 = lower freauncy.
Hope this helps you.
