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.

Participant	24 hours	36 hours	48 hours
A	0	1	5
B	0	0	0
C	1	3	5

1. In this specific scenario, what is the independent variable? Is it between or within subjects? How many levels does it have, and what are they?

The independent variable is the number of hours of sleep deprivation. This is between subject test since we are comparing the number of errors made with the number of hours of sleep deprivation. There are three levels, and they are: 24 hours vs 36 hours, 24 hours vs 48 hours and 36 hours vs 48 hours.
