How to generate an TRIMMEAN FUNCTION formula using AI.

To obtain information on the ARRAY_CONSTRAIN formula, you could ask the AI chatbot the following question: “ To get the TRIMMEAN formula, you can ask the AI chatbot: "What is the Excel formula for calculating the trimmed mean?"

TRIMMEAN FUNCTION formula syntax

The TRIMMEAN function in Excel calculates the trimmed mean of a data set, which is the average of values after excluding a specified percentage of outliers from both ends of the data. The syntax for TRIMMEAN is: TRIMMEAN(array, percent) - array: The range of cells or array containing the data set. - percent: The percentage of data to exclude from both ends. It should be a decimal value between 0 and 1. For example, if you have a data set in cells A1 to A10 and want to calculate the trimmed mean excluding 10% of outliers, you can use the formula: =TRIMMEAN(A1:A10, 0.1) This will return the trimmed mean of the data set after excluding 10% of the highest and lowest values.

Use Cases & Examples

In these use cases, we use the TRIMMEAN function to calculate the trimmed mean of values in a range. The TRIMMEAN function is useful when we want to calculate the mean of a range while excluding a certain percentage of outliers from the calculation.
