Chebyshev Interval Lower And Upper Bound Calculator

Introduction & Importance

Chebyshev’s inequality is a fundamental concept in statistics, providing a bound for the probability that a random variable deviates from its expected value. Our calculator helps you find the lower and upper bounds of a Chebyshev interval for your data.

How to Use This Calculator

1. Enter the mean and standard deviation of your data.
2. Select the desired confidence interval (90%, 95%, or 99%).
3. Click ‘Calculate’.

Formula & Methodology

The Chebyshev interval is calculated using the formula: mean ± k * standard deviation, where k is determined by the selected confidence interval.
