Summarize a numeric data set with mean, population standard deviation, and sample standard deviation.
Keep a record of the assumptions behind the result and compare nearby scenarios before making a decision.
Population SD = √[Σ(x − mean)² ÷ n]; sample SD uses n − 1.
This result reflects only the values and assumptions shown above. It does not automatically include taxes, fees, market changes, local rules, or personal circumstances unless those inputs are explicitly present.
These are demonstration assumptions, not market data or a recommendation. Use Reset example above to reproduce this result, then replace the values for your own scenario.
Example result: 4.427189 population SD
The example is fixed while your live result above changes. Differences in display rounding do not change the underlying calculation.
Replace the examples with your real values. Results update instantly as inputs change.
Try conservative, baseline, and optimistic inputs to see whether the conclusion holds.
Review the formula and limitations, then verify important decisions with authoritative sources.
Population SD = √[Σ(x − mean)² ÷ n]; sample SD uses n − 1.
Use population SD for a complete population and sample SD when the observations are a sample used to estimate a population.
