Data Separators allowed: commas, spaces, tabs, semicolons, newlines. Non-numeric tokens are ignored.

Variance/SD

Mode rule

Weights

1) What separators can I use?

Use commas, spaces, tabs, semicolons, or newlines. The tool normalizes them automatically and ignores stray text.

2) How do I enter a frequency table?

Select “Value, Frequency” and put each pair on its own line, like 10 3 to mean the value 10 appears three times.

3) How do weighted values work?

Pick “Value, Weight”, enter pairs, and the calculator will compute a weighted mean. You can normalize weights or treat them as already summing to 1.

4) What’s the difference between sample and population variance?

Sample variance divides by n−1 to remove bias when data is a sample. Population variance divides by n when the dataset is complete.

5) Why are geometric and harmonic means sometimes unavailable?

Geometric mean needs all values > 0. Harmonic mean cannot include zero because it requires reciprocals.

6) What does Trim % do?

It chops equal proportions from both tails of the sorted data before averaging, reducing the influence of outliers.

7) How is the mode chosen when multiple values tie?

By default, all modes are reported. Switch “First mode only” to see just the first in ascending order.
