Q3 of 71 Page 204

Calculate the mean of the following distribution by assumed mean method:

Here first we’ll find the class marks -



We’ll first assume a mean A = 225 and here h = 175 - 125 = 50.


Now we’ll find the ui



Now,


Where, = Mean, ui = calculated values of x and fi = frequency for that x.





⇒ = 266.25
