It is used in salary, population, and many other similar statistics, where estimates are calculated using a sample. Descriptive statistics, by contrast, may be used to describe a sample or the whole population,…

Is inferential statistics based on probability theory?

Inferential Statistics is used to determine the probability of properties of the population on the basis of the properties of the sample, by employing probability theory. The major inferential statistics are based on the statistical models such as Analysis of Variance, chi-square test, student’s t distribution,…
