Questions: Determine whether this study is an observational study or an experiment. Explain. A research study compared the memory retention of subjects when a learning activity was followed by a brief period of wakeful rest and when a learning activity was followed by a brief period of distraction. The study is because it a treatment to the subjects.

Transcript text: Determine whether this study is an observational study or an experiment. Explain. A research study compared the memory retention of subjects when a learning activity was followed by a brief period of wakeful rest and when a learning activity was followed by a brief period of distraction. The study is _________ because it _________ a treatment to the subjects.

Solution

Solution Steps

Step 1: Identify the Type of Study

To determine whether the study is an observational study or an experiment, we need to assess whether the researchers actively manipulated any variables or simply observed the subjects without intervention.

Step 2: Analyze the Study Description

The study description states that the researchers compared memory retention under two different conditions: one where a learning activity was followed by a brief period of wakeful rest, and another where it was followed by a brief period of distraction. This implies that the researchers assigned specific conditions to the subjects.

Step 3: Determine the Nature of the Study

Since the researchers assigned different conditions (wakeful rest and distraction) to the subjects, this indicates that the study involved manipulation of variables, which is characteristic of an experiment.
