Student's T-Test And The Glasgow Coma Scale, Joseph Lucke
Student's T-Test And The Glasgow Coma Scale, Joseph Lucke
Joseph Lucke
Study Objective: To explore how Student's t test, which assumes normal errors, is affected by the nonnormal distribution of Glasgow Coma Scale (GCS) scores.
Methods: A sample of 145,295 GCS scores from the Pennsylvania Trauma Systems Foundation was assumed to represent the true GCS distribution. Four Monte Carlo simulations, each based on 40,000 replications, were conducted to approximate the distribution of t values arising from samples drawn from the GCS distribution, using sample sizes of 10, 30, 60, and 100 per group.
Results: The histograms of t values derived from the GCS distribution resembled the corresponding Student t distributions for …
