APFIVE Circadian Rhythm and Reaction Time Data
In a sleep study examining circadian rhythm disruption, researchers measured participants’ reaction times (in milliseconds) at four different times during a 24-hour period. The data for 8 participants shows: 8am: 245, 238, 242, 240, 236, 244, 241, 239; 2pm: 236, 232, 235, 233, 230, 237, 234, 231; 8pm: 248, 245, 247, 244, 242, 249, 246, 243; 2am: 289, 285, 288, 286, 283, 290, 287, 284. What is the percentage increase in mean reaction time between the fastest and slowest times of day?
