Statistics Concept Introduction

Introduction:

Sampling distribution:

It is the distribution of observations obtained by using the statistic of all the possible samples taken from the population. Here, the size of the all possible samples is same.

Parameter:

A parameter is a value that explains the characteristic of the population. In general, the parameter is estimated by using the sample, because it is difficult to examine the total population.

Statistic:

A statistic is a value that explains the characteristic of the sample. It can be obtained by using the sample of observations.
