A group of researchers is planning an experiment to test the hypothesis that sleep deprivation decreases memory retention. All participants will have a practice session in which they memorize words. That night they will sleep in a monitored lab for a specified time that depends on their group. T each participant will be tested on how many words they remember from the practice session. The researchers are deciding what conditions they should manipulate for the experimental group. Q3.7. The table below shows conditions for the control group and three possible experimenta groups. Which experimental group should the researchers use to compare to the control gro in order to test their hypothesis? Number of hours of sleep Days between practice and testing Length of practice session Control Group 8 hours 1 day 30 minutes Experimental Group 1 4 hours 3 days 30 minutes Experimental Group 2 8 hours 1 day 45 minutes Experimental group 1 Experimental group 2 Experimental group 3 O None of the experimental groups are appropriate for testing their hypothesis. Experimental Group 3 4 hours 1 day 30 minutes

A group of researchers is planning an experiment to test the hypothesis that sleep deprivation
decreases memory retention. All participants will have a practice session in which they memorize
words. That night they will sleep in a monitored lab for a specified time that depends on their group. Then
each participant will be tested on how many words they remember from the practice session. The
researchers are deciding what conditions they should manipulate for the experimental group.
Q3.7. The table below shows conditions for the control group and three possible experimental
groups. Which experimental group should the researchers use to compare to the control group
in order to test their hypothesis?
