CI Standard deviation calculator

This calculator determines the standard deviation, mean, and variance for a set of numbers, distinguishing between sample and population data. It is designed for students, researchers, and professionals who need to analyze data variability and understand the underlying calculations. The tool provides a clear breakdown of the process, making it suitable for both learning and practical statistical analysis.

• Step-by-Step Calculations: The tool shows every intermediate step, from summing the data points to the final square root, allowing you to follow and verify the entire statistical process.
• Sample and Population Modes: It correctly applies the different formulas for sample data (using n-1) and population data (using N), ensuring accurate results for your specific dataset.
• Comprehensive Output: In addition to standard deviation, it calculates and displays the mean, variance, sum of squares, and count, giving a complete summary of your data's distribution.
• Simple Data Entry: You can input a list of comma-separated numbers directly, making it quick to get results without complex formatting or setup.
