Trial analyzer

Keep the individual observations beside their summaries.

Enter up to 100 nonnegative measurements. The sample values are invented.

A comparison worth making

Try the second invented dataset: 3.2, 6.4, 4.5, 7.0, 3.9. Both datasets have mean 5.0 meters, but their ranges differ. Explain why that could matter for a question about consistency.

The tool calculates descriptive summaries. It does not test statistical significance, detect every recording error, or establish which fold caused a difference.
