Correlation is a statistical tool used to study the relationship between two or more variables. Two variables are said to be correlated if the

Mean Deviation Definition

Mean deviation is defined as the mean of absolute deviations of the values from the central value.

For individual series:

\[MD\left( \overline{X}

Definition of Quartile Deviation

Quartile Deviation divides the total frequency in to four equal parts. The lower quartiles Q1 refers to the values of variates

Definition

Range is the simplest method of studying variation. It represents the differences between the values of the extremes. It is the difference between the

What is Standard Deviation?

Standard deviation is the root of sum of the squares of deviations divided by their numbers. It is also called ‘Mean
