Question

The standard deviation of two observations a and b is

Answer 1

Answer:

the stranard deviations of any two observation a and b(>a) is

Answer 2

As we know that standard deviation help to measure the amount of variation of a set of values.

Given: Standard deviation of two observations a and b.

The Mean of the two observations,

$\mu=\frac{a+b}{2}$

Standard Deviation S,

$S=\sqrt{\frac{(a-\mu)^2}{2-1}}$

$S=a-\mu$
