#12: A researcher is attempting to determine the effects of practice and gender on a times task.         Participants in an experiment are given a computerized search task.  They search a         computer screen of various characters and attempt to find a particular character; they press a         button to stop a timer. Their reaction time (in seconds) on each trial is recorded.   Subjects         practice for 2, 4 or 6 hours and are either female or male. The reaction time data for the 30         subjects appear here.
