Xi is data value of x. Apart from calculating covariance, it also calculates the mean value for a given data set. Web to calculate covariance of a sample, use the formula: Web the use of this calculator is simple: Cov (x,y) represents the covariance of sample x and covariance of sample y.
Where $\mu_x$ and $\mu_y$ are the population means. Σ (xi) = μ, which represents the expected mean (average) value for your x values. If x and y have a positive covariance, then when x is large y is also large. It also shows the expected value (mean) of each random variable.
It assists us in comprehending the relationship between two data sets. Here, you will learn how the covariance formula works, how to calculate covariance, and understand the covariance vs correlation relationship. The number of values you enter in this sample mean and covariance calculator should be same for both x and y.
