Question

What is the reason behind taking mid values as assumed mean?​

Answer 1

Step-by-step explanation:

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
