KOVARYANS.S | COVARIANCE.S |
The COVARIANCE.S
function, known as KOVARYANS.S
in Turkish, is a statistical function used to measure the strength of the relationship between two sets of data. This function is available in both Microsoft Excel and Google Sheets. It calculates the variance between two data series, essentially measuring how much these series vary together.
Syntax of KOVARYANS.S Function
The general syntax for this function is as follows:
=KOVARYANS.S(array1, array2)
- array1: The range of cells that contains the first dataset.
- array2: The range of cells that contains the second dataset. It must contain the same number of data points as array1.
Practical Examples
Below are some practical examples of how the KOVARYANS.S
function can be used.
Example 1: Relationship Between Advertising Budget and Sales Volume
A company wants to analyze the impact of its advertising budget on sales volume using data from the past 8 months:
| Month | Advertising Budget ($) | Sales Volume | |-----------|------------------------|--------------| | January | 1000 | 300 | | February | 1500 | 350 | | March | 1200 | 345 | | April | 1000 | 320 | | May | 1300 | 330 | | June | 1600 | 365 | | July | 2000 | 400 | | August | 1800 | 390 |
The covariance between these two datasets can be calculated using:
=KOVARYANS.S(B2:B9, C2:C9)
Example 2: Temperature Changes and Refrigerator Sales
In another example, we will examine the impact of temperature increases on refrigerator sales during the summer months. Here are the temperature and refrigerator sales data for the last six months:
| Month | Average Temperature (°C) | Refrigerator Sales | |----------|---------------------------|--------------------| | June | 25 | 150 | | July | 29 | 180 | | August | 33 | 210 | | September| 30 | 200 | | October | 24 | 170 | | November | 22 | 130 |
Let”s calculate the covariance between these two data series:
=KOVARYANS.S(B2:B7, C2:C7)
As seen in these examples, the KOVARYANS.S
function is very useful for measuring the strength of the relationship between different data arrays, especially in the fields of economics and social sciences.
