Question

Identify the symbols used for each of the following: (a) sample standard deviation: (b) population standard deviation; (c) sample variance; (d) population variance.

a. The symbol for sample standard deviation is__

b.The symbol for population standard deviation__

c. The symbol for sample variance is__

d. The symbol for population variance is__

Answer 1

Answer:

a) The symbol for sample standard deviation is S

b) The symbol for population standard deviation is б (sigma)

c) The symbol for sample variance $S^{2}$

d)The symbol for population variance is $б^{2}$

Step-by-step explanation:

Step 1:-

Population:-  Population consists of the total of the observations with which we are concerned.

Parameters:-  The statistical constants of the population namely mean , variance$б ^{2}$ and standard deviation 'б '

Sample:-  A sample is a subset of a Population

statistics:-

he statistical constants of the sample namely mean , variance$S ^{2}$ and standard deviation 'S '

step2:-

a) The symbol for sample standard deviation is S

b) The symbol for population standard deviation is б (sigma)

c) The symbol for sample variance $S^{2}$

d)The symbol for population variance is $б ^{2}$
