# ForceDecks Tests: Countermovement Jump Metrics

Each of the following metrics are automatically calculated immediately after a test is completed. Results are reported for:

- Individual Reps;
- Maximum;
- Mean;
- Standard Deviation (SD);
- Coefficient of Variation (CoV); and
- Standard Error Measurement (SEM)
