Convert raw numbers into descriptive statistics, confidence intervals, and percentile insights.
Paste values separated by commas, spaces, or line breaks. Useful for exam prep, operational metrics, experiment results, and report validation.
Parsed values: 9
Mode: 24
z = -0.061314
72.222222th percentile
Formula: mean ± z × (sample SD / √n)

Use population variance/SD when the dataset contains every observation in scope. Use sample variance/SD when your list is a subset of a larger population and you want an unbiased estimate.
A z-score near 0 means the value is close to the mean. Larger absolute z-scores indicate more unusual observations relative to the dataset spread.
Does this tool support negative and decimal values? Yes. You can mix negatives, decimals, and scientific notation like 2.5e3.
What if all values are unique? In that case there is no repeated mode, so the mode output stays empty by design.
