Question

If we take the actual mean as the assumed mean, how much will be?
ahonnabing any mid value (class mark) as assumed mean?​

Answer 1

Answer:

It is not necessary to consider mid value as assumed mean. One can take any value as assumed mean.

The reason why mid-value is taken into consideration is

Nearly half of the values will be less than assumed mean and hence the difference between assumed mean and x value will be negative

And remaining half values will be more than assumed mean and hence the difference between assumed mean and x value will be positive

And hence, one gets smaller numbers as a sum of ‘fx’ which makes calculation easier
