This question, and the questions that follow (through Question #10) pertain to Problem #1 (ANOVA) from your calculation sheet. A researcher desinged a study to answer the question: Does sleep deprivation (preventing people from sleeping for an extended amount of time) have an effect on attention? Participants were randomly assigned to one of three groups: The first group (X1) was not deprived of any sleep (they were tested immediately upon waking). The second group (X2) was deprived of sleep for 24 hours. The third group (X3) was deprived of sleep for 48 hours. After being deprived of sleep (or not), participants completed a psychomotor vigilance task (PVT), which requires participants to press a button in response to a light at random intervals. Failure to press the button in response to the light is recorded as an error. The raw scores on your calculation sheet (Problem #1) represent the number of errors for each participant. Is this an experiment or a quasi-experiment? Explain your answer.
