Covariance is a term that is commonly used in mathematics and statistics. What is covariance? The covariance shows a relationship between the two variable values. In simple words, covariance is a parameter that tells how two variable values (x, y) can have variation together. It is similar to the variation of the values thus measures it accurately. A covariance calculator is a digital tool that helps a person in assessing covariance in a matter of seconds with high accuracy and convenience.
How to calculate covariance?
The covariance calculation is attainable with the help of the covariance formula which is mentioned below:
Sample Covariance (X,Y) = Σ E((X-μ)E(Y-ν)) / n-1
Where,
X and Y = variable values
n = total number
μ = expected value of X
ν = expected value of Y
Remembering the formula for every statistical analysis is not an easy job so the covariance calculator and other digital tools provide help in this regard.
Calculation with covariance calculator:
access the tool from the internet ...
... and set the parameter for which you are going to calculate covariance. There are three possible categories for this:
1. from a dataset
2. from a correlation coefficient
3. covariance matrix.
Furthermore, you need to add the data set of X and Y. click on “calculate”, and you will get the required answer in a blink of an eye. The manual calculation for the covariance is a bit confusing because of the complex formula. The covariance calculator has a built-in formula that processes the input values automatically. The students find it quite useful for the long assignments and homework as it saves time and effort. It also helps the students in practicing the formulas and make good speed in working. The timely approach of the tool makes it impressive for the professionals as well.
