Descriptive statistics
Sample variance = Σ(x − x̄)² / (n − 1) Population variance = Σ(x − μ)² / n
The panel lists both sample and population metrics so you can match classroom or professional conventions.
How to use

- Toggle between sample or population mode to change the denominator.
- Read the summary card for central tendency and spread values instantly.
Example
Input: Data = 12, 14, 18, 20, 26
Output: Sample σ ≈ 5.20, Population σ ≈ 4.65, Mean = 18
FAQ & notes
How are blanks or text handled?
Non-numeric entries are ignored so pasted spreadsheets or notes do not disrupt the calculations.
What is the difference between sample and population mode?
Sample mode divides by n − 1 to remove bias when working with a subset, while population mode divides by n for complete datasets.
