Do you know How to use TRIMMEAN in Google Sheets? For the purpose of calculating the mean of a dataset in Google Sheets, the TRIMMEAN function is utilised. This function is used to exclude a certain proportion of the data from the high and low ends of the dataset. Google Sheets‘ TRIMMEAN function is a statistical tool that can be used to calculate the mean of a dataset while excluding a specific percentage of the data from the calculation.
This can be accomplished by excluding the data from the calculation. The use of this is beneficial in the event that your dataset contains outliers that you would like to exclude from the calculation of the mean. One of the reasons why this function is useful is that it assists you in locating and removing outliers from a particular data set, as well as returning the mean or average.
An argument known as the percent argument is included in the TRIMMEAN function. This argument gives the user the ability to specify the percentage of data points that should be excluded from the top and bottom of the set. In the following tutorial, we will walk you through the process how to use TRIMMEAN in Google Sheets.
What is the trimmed mean?
It is possible to calculate the mean (average) of a dataset using the TRIMMEAN function in Google Sheets. This function does this by excluding a specific percentage of the values that are the smallest and largest. In other words, before calculating the mean, it eliminates some of the extreme values that are located at both ends of the data.
After excluding a certain percentage of data points from both ends of a dataset, the TRIMMEAN function in Google Sheets is utilised to compute the mean (average) of the dataset. This is done after the initial data points have been removed. This function is helpful in situations where you want to lessen the influence that outliers or extreme values have on the mean that you have calculated.
How to use TRIMMEAN in Google Sheets
- Open your Google Sheets document.
- Select the cell where you want the result of the TRIMMEAN function.
- Type “=TRIMMEAN(” and select the range of cells you want to include in the calculation.
- Close the parentheses and press Enter.
Why use TRIMMEAN in Google Sheets?
- Outlier Removal: If your dataset has outliers or very high or very low values that could have a big effect on the mean, TRIMMEAN lets you leave out a certain percentage of the data from both ends. This gives you a more accurate measure of the central tendency.
- Not Affected by Extreme Values: TRIMMEAN is not as affected by extreme values as the regular mean. This can be helpful when you want a more stable measure because extreme values could change the average.
- Robust Estimation: If your data is constantly changing, TRIMMEAN can help you get a more accurate estimate of the central tendency by taking out a certain percentage of the data.
- LOWERING SENSITIVITY: TRIMMEAN lets you find a more stable average that is less affected by extreme values when they are likely to happen because of measurement errors or other reasons.
- More accurate representation of the data: TRIMMEAN can give a more accurate average for datasets with a lot of variation by focusing on the middle part of the data distribution.
Comparing TRIMMEAN with Other Statistical Functions
| Function | Description | Use Case |
|---|---|---|
| TRIMMEAN | Calculates the mean excluding a percentage of data | Useful when outliers significantly impact data |
| AVERAGE | Calculates the average of a range of numbers | Simple measure of central tendency |
| MEDIAN | Finds the middle value in a range of numbers | Less sensitive to extreme values |
| MODE | Identifies the most frequently occurring value | Applicable when looking for common values |
| STDEV | Calculates the standard deviation of a dataset | Measures the amount of variation in data |
| COUNT | Counts the number of cells that contain numbers | Provides the count of valid data points |

Conclusion
For the purpose of determining the trimmed mean of a set of values, the TRIMMEAN function in Google Sheets is utilised. After removing a specific percentage of the highest and lowest values from a dataset, the trimmed mean is a statistical measure that determines the average of the dataset after excluding the dataset. If you want to calculate the trimmed mean for this range of values, then this is the range you should use. A range of cells or an array of values can be used to represent it.
Questions and Answers
If you want to cut cells, select them first. On your keyboard, cut the cells by pressing the Ctrl+X (Windows) or Command+X (Mac) keys simultaneously. Prior to the cells being pasted, the contents of the cells will continue to be stored in their original location.
You can undo the most recent action by clicking the Undo button located on the toolbar. Hold down the Ctrl key and press Z. Your previous action has been reversed. For instance, if you had deleted an item and then changed your mind and decided that you should keep it after all, undoing the deletion would bring it back into existence.
Through the use of Google Docs, Sheets, and Slides, it is possible to locate and replace specific words within a presentation, spreadsheet, or document. Utilising the keyboard shortcut Ctrl + f (or ⌘ + f on a Mac), it is also possible to conduct a search within a file.
