Answer 1

ANSWER:-

In statistics the assumed mean is a method for calculating the arithmetic mean and standard deviation of a data set.

It simplifies calculating accurate values by hand.

Assumed mean is used to calculate the actual mean as well as the variance and standard deviation as we'll see later.

if we count frequencies available,say n. If it's odd number then

(n+1)/2 th frequency is the assumed mean. If it's even, one can choose either

(n/2) or (n/2)+1 th number as the assumed mean.

Answer 2

Step-by-step explanation:

$\frac{n}{2} \: or \: ( \frac{n}{2} ) + 1 \: th \: number \: as \: the \: assumed \: mean$
