It has been suggested that pupil size increases during emotional arousal. A researcher would, therefore, like to see whether the increase in pupil size is a function of the type of arousal (pleasant versus aversive). A random sample of five participants is selected for the study. Each participant views all three stimuli: neutral, pleasant, and aversive photographs. The neutral photograph portrays a plain brick building. The pleasant photograph consists of a young man and woman sharing a large ice cream cone. Finally, the aversive stimulus is a graphic photograph of an automobile accident. Upon viewing each stimulus, the pupil size is measured (in millimeters) with sophisticated equipment. The data are as follows. Use it to test whether pupil size varies based on type of arousal.

	Stimulus
Participant	Neutral	Pleasant	Aversive
A	4	8	3
B	3	6	3
C	2	5	2
D	3	3	6
E	3	8	4

The following data were obtained from a research study examining the effect of sleep deprivation on motor skills performance. A sample of five participants was tested on a motor-skills task after 24 hours of sleep deprivation, tested again after 36 hours, and tested once more after 48 hours. The dependent variable is the number of errors made on the motor-skills task, shown below. Use the data to test whether or not the number of hours of sleep deprivation has a significant effect on motor skills performance.

A psychologist at a private mental health facility was asked to determine whether there was a clear difference

in the length of stay for patients with different categories of diagnosis. Looking at the last seven patients in

each of the three major categories, the results (in terms of weeks of stay) were as follows. Using the data

below, test whether the length of stay for patients vary based on category of diagnosis.
