Deviation Index Calculator

Deviation Index Calculator calculator can be used to measure the relative variability of a dataset by comparing the standard deviation to the mean.

Input Parameters

Calculation Results

Calculation Formula

Deviation Index (DI) = Standard Deviation / Mean

Where:
- Standard Deviation is the square root of the variance
- Mean is the average of the dataset

Mean: -
Standard Deviation: -
Deviation Index (DI): -

How to Use the Deviation Index Calculator

  1. Enter your dataset in the input field. Separate each number with a comma (e.g., 10, 20, 30, 40, 50).
  2. Click the "Calculate" button to compute the mean, standard deviation, and deviation index.
  3. The results will be displayed in the corresponding fields.
  4. If you want to start over, click the "Reset" button.

Understanding the Deviation Index

The Deviation Index (DI) is a measure of relative variability. It is calculated by dividing the standard deviation by the mean. A higher DI indicates greater variability in the dataset relative to its mean.

When to Use the Deviation Index

The Deviation Index is useful in various fields such as finance, economics, and quality control to understand the spread of data relative to its average value. It is particularly useful when comparing datasets with different units or scales.
