Experience Based Mitigation1
Online Inferential Statistics Appendix
The following analyses is meant to accompany Nunes & Kramer (submitted). Experience based mitigation of age-related performance declines: evidence form air traffic control. We note that tests of the skewness and kurtosis of the resulting distributions did not reveal any significant departures from normality (see Tabachnick & Fidell, 1996). All dfs are all (1,68) unless otherwise noted.
