A scientist has formed the following hypothesis: Students who listen to music while studying will take longer to complete their reading and remember less of it. Once she has constructed her hypothesis, what are the three steps that she should follow to complete her experiment? State the steps and give an example of how to complete each step
What will be an ideal response?
The first step is to devise a method to test the hypothesis. One way to assign students randomly to two groups, one of which listens to music and one that does not.
The next step is to collect results. In this case, she might ask each student to record the time he or she started reading and the time of finishing. At one or more later times she would administer tests of how well students in the two groups remembered the material.
The final step is to interpret the data and determine what the results mean. If the students listening to music took longer to finish and remembered less, then she gains confidence in her hypothesis. However, she should try to replicate the result, possibly using different types of music or different types of reading. If the groups did not differ, or if the group listening to music remembered more, then she should abandon or modify her hypothesis.
