- Outcome: The MIN operate returns the bottom numerical worth from the required vary.
By using the MIN operate, we will effectively establish the minimal worth in our information vary. This worth represents the opposite finish of the vary spectrum and performs a vital function in calculating the distinction between the best and lowest values.
With each the utmost and minimal values decided utilizing the MAX and MIN features, we are actually able to calculate the vary by subtracting the minimal worth from the utmost worth. This easy but efficient method will present us with the vary of our information, quantifying the extent of its unfold and variability.
Subtract MIN from MAX
The ultimate step in calculating the vary in Excel is to subtract the minimal worth (obtained utilizing the MIN operate) from the utmost worth (obtained utilizing the MAX operate). This easy subtraction operation yields the vary of the information.
To carry out this subtraction, you need to use the next method:
Vary = MAX – MIN
For instance, if the utmost worth in your information vary is 100 and the minimal worth is 50, the vary will be calculated as follows:
Vary = 100 – 50 = 50
This outcome signifies that the information is unfold out over a spread of fifty models. A bigger vary typically signifies better variability inside the information, whereas a smaller vary suggests a extra concentrated distribution.
The vary worth serves as a helpful measure of the general unfold of your information. It may be used for varied functions, resembling:
