# How the concepts of covariance differ from factorial?

## What is Covariance?

Before we learn how Covariance differs from Factorial, let’s clear ourselves that what is Covariance? As we are talking mathematically, the property of a function of retaining its form when the variables are linearly transformed. Covariance measures the direct relationship between the returns on two or more assets.

Covariance designates the relationship of two variables whenever one variable changes. Now talking about theory and statistics, covariance is a measure of the joint variability of two random variables which you may calculate manually by using formula’s or also you can calculate covariance online.

The formula of Covariance is a statistical formula that is used to assess the relationship between two variables. The Covariance of ‘Whether two variables vary or change together or they associated and assists together’.

## What is factorial?

Now to know how Covariance differs from a factorial, we also have to know more about Factorial.

A definition describes factorial simply and is the product of an integer and Factorial is the operation of multiplying the natural number (any) with all the natural numbers that are lesser than it.

which sums up this mathematical equation: n! = n * (n-1) * (n-2) * (n-3).

By using such a mathematical equation, the factorial sequence calculator helps us to find the factorial of any number online.

Factorial is also used for all the questions that ask you to find how many ways you can arrange or order a set number of things. The zero is factorial is assigned the value of one: Factorial four is 1 × 2 × 3 × 4.

We can also use factorials in real life; we use factorials when we look at permutations and combinations. Permutations tell us how many different ways we can arrange things if their order matters while combinations tell us how many ways we can choose k item from n items if their order does not matter.

## How do the concepts of Covariance differ from Factorial?

There are many differences between Covariance and Factorial, but the main difference between Covariance and Factorial is that the Factorial is a categorical variable; however, Covariance is a continuous variable.

An Analysis of Covariance (ANCOVA), the categorical independent variable is termed as a factor, while the interval natured independent variable is termed as a covariate.

The positive Covariance reflects the asset returns that move together while a negative covariance means they move inversely. Whereas, all integers below it or the Factorial of a positive integer n, denoted by n! is the batch of all positive integers lower than or equal to the value of n. An example can given to be more precise; an example is that factorial four (4!) is equal to 24.

The concept of Covariances measures the directional relationship between the returns on two assets. While the concept of factorials is the product of all positive integers less than or equal to a given positive integer while being it has denoted by that integer and an exclamation point as well.

### Factorial Representation

What is the Factorial function, you may ask? Well, the factorial function is a mathematical formula that we represent by an exclamation mark “!”. Talking of Factorial formula it is simple once you learn it by heart in this formula, you must multiply all the positives and integers that exist between the number that visible in the formula and the number 1.

### Covariance Representation

Whereas it evaluates “how the mean values of the two variables move together.” These can represented by:

XI = a given value of x in the data set,

XM = the mean, or average, of the x values,

YI = the given value of y in the data set that corresponds with x.i,

YM = the mean, or average, of the y values,

N is the number of data points.
