The 10 Trimmed Mean Calculator is a statistical tool used to analyze a set of data by eliminating extreme values. It computes the trimmed mean by excluding a specified percentage of the lowest and highest values, providing a more robust measure of central tendency than the traditional mean.
Formula of 10 Trimmed Mean Calculator
The formula for the Trimmed Mean is straightforward:
Trimmed Mean = (Sum of data values after trimming) / (Number of data values after trimming)
In this formula:
- "Sum of data values after trimming" refers to the sum of the data values after removing a specified percentage of the lowest and highest values.
- "Number of data values after trimming" refers to the count of data values that remain after trimming.
Table of General Terms
| Term | Description |
|---|---|
| Mean | The arithmetic average of a set of numbers. |
| Trimmed Mean | The mean after excluding a certain percentage of extremes. |
| Central Tendency | A statistical measure that represents the center of a data distribution. |

Example of 10 Trimmed Mean Calculator
Let's consider a dataset: 5, 8, 10, 12, 15, 20, 25, 30, 35, 40.
By trimming 10% of the lowest and highest values (1 value each), the calculation would involve excluding 5 and 40. Thus, the trimmed dataset becomes: 8, 10, 12, 15, 20, 25, 30, 35. The trimmed mean would then be calculated based on this subset of values.
Most Common FAQs
A: The Trimmed Mean is less affected by outliers or extreme values, providing a more robust measure of central tendency in datasets where such values may skew the results.
A: The percentage you want to trim depends on the dataset and the degree of outliers present. Common values you can use are between 5% to 25%, but the choice should reflect the characteristics of the data you are analyzing.
