Reaction Time Across a Training Programme
Research information
Statement of the problem
This study examines how participants' reaction time changes over a training programme, with the same participants measured repeatedly at three sessions.
Objectives
- To describe the reaction_time_ms of the participants.
- To determine whether reaction_time_ms differs across the repeated sessions (baseline, week 4, and week 8).

The result is statistically significant (p = 0.0000 < 0.05).
Sphericity was violated (Mauchly's test was significant); the Greenhouse-Geisser correction was applied to the degrees of freedom, and the corrected p-value is reported alongside the uncorrected result.
