Formula and method
Assumptions and limitations
Use your own matching-period observations. These descriptive calculations are not forecasts, investment advice or a national dataset. Lists accept up to 100 comma-separated numbers; do not enter thousands separators.
Worked example
For the sample inputs shown above, financial data summary produces a first result of approximately 3. The assumptions below explain what this result represents.
What the result means
Inspect count, mean, median, range and both sample and population dispersion for financial observations.
Common questions
How is the calculation performed?
Mean = sum / n; sample variance = sum of squared deviations / (n−1); population variance divides by n. Median uses sorted central values.
What does the model leave out?
Use your own matching-period observations. These descriptive calculations are not forecasts, investment advice or a national dataset. Lists accept up to 100 comma-separated numbers; do not enter thousands separators.
