Basically correlation is the measurement of the strength of a linear relationship between two variables say x and y.

An equation consisting of a differential coefficient is called a differential equation.

Simpson’s rules are very useful in numerical integration to evaluate such integrals.

Moments are the statistical tools used to describe the characteristics of a distribution. moments are the arithmetic means of first, second, third and fourth.

the correction between these n pairs of rank is called the rank correlation in the characteristics A and B for that group of individuals.

The concept of probability distribution gives the idea about the probabilities of any random experiment.

When one task is to be assigned to one person in such a way that the total person hours are minimized, then this kind of problem is known as assignment problem.

The method of variation of parameters is the general method which we use to find out a particular solution of a differential equation by replacing the constants in the solution of the homogeneous differential equation by functions and evaluating these functions so that the original DE will be satisfied.

Numerical integration is the method to calculate the approximate value of the integral by using numerical techniques.
