Question

A researcher is interested in determining the effects of sleep deprivation on the length of time it takes rats to correctly travel a maze to its end point. The researcher wants to know whether the amount of sleep deprivation makes a difference in the speed with which the rats correctly travel the maze. The researcher begins with twenty rats and randomly assigns them to one of two groups such that there are ten rats in each group. One group of 10 rats is sleep deprived for 24 hours prior to performing in the maze, and the second group of 10 rats is sleep deprived for 36 hours before performing in the maze. The researcher records the length of time (in seconds) it takes for each rat to correctly run the maze. The following data were recorded for each rat in each group: Group 1 (24 hour deprivation) 8 10 14 12 Group 2 (36 hour deprivation) 14 12 16 16 12 16 14 9 13

Explanation / Answer

Since the two groups are independent, we have to employ

independent t-test in this case. (Ans).
