|See also: One-Sample t-Test, two-sample t-test|
The reaction time of a person is of much importance in many critical situations. It is also well-known that the reaction time is strongly influenced by the consumption of alcohol or by the degree of fatigue. In order to decide whether the reaction time of a person is above some predefined threshold, a one-sample t-test should be applied. In order find significant differences for different experimental set-ups, a two-sample t-test should be used.
9 persons have repeated a reaction test on two different occasions between
10 and 40 times. The first test run was performed in early afternoon at
the beginning of a two-hour course in statistics (column denoted by "t-early").
The second series of tests were conducted after the two-hour course ("t-late").
