Understanding the relationship between two variables is key in statistical analysis, and covariance is a measure of how much two variables change together. Excel, as a versatile tool, provides functions that allow users to calculate covariance, though the process involves multiple steps.
On this page, we'll outline the steps to compute covariance in Excel. For a simpler approach, we'll explore how Sourcetable's AI chatbot can instantly analyze your data, generate visualizations, and calculate covariance by simply asking it what you want to know - try it now to answer any spreadsheet question effortlessly.
The COVARIANCE.P function in Excel calculates the population covariance, which signifies the relationship between two data sets. It determines how much two variables change together and is the average of the products of deviations for each data point pair.
Before applying the COVARIANCE.P function, ensure your data is numeric, as it ignores text, logical values, and empty cells, and includes cells with the value zero. The two arrays, array1 and array2, must have an equal number of data points to avoid the #N/A error.
To execute the COVARIANCE.P function, input two arguments that are either numbers, names, arrays, or references containing numbers. Avoid empty arrays to prevent the #DIV/0! error. Covariance can analyze trends, such as determining if an increase in education correlates with higher income levels.
When using COVARIANCE.P, consistent data array sizes are crucial, as mismatched arrays result in a #N/A error. Moreover, providing non-empty arrays is essential to circumvent the #DIV/0! error.
Simply insert ‘=COVARIANCE.P(array1, array2)’ into a cell and replace array1 and array2 with your data range or references. This Excel feature provides a swift and reliable method to understand the interdependence of two data sets.

Use the COVARIANCE.P function with two arrays of data. The syntax is =COVARIANCE.P(array1, array2) where array1 and array2 are ranges of integer values.
Both array1 and array2 arguments are required, must contain integer values, and must have the same number of data points. The function will ignore text and logical values.
The function returns #N/A if array1 and array2 have different numbers of data points, and returns #DIV/0! if either array1 or array2 is empty.
