Question

An expimenter wants to know if listening to classical music will help people to solve more math problems. The expimenter has a group of people come in for the study in the morning, and plays them classical music while they solve math problems. The expimenter then has a group of people come in for the study in the afternoon, and has them solve math problems with no music playing. What did the expimenter fail to do

Answer 1

to provide common conditions of research

Step-by-step explanation:

In simple words, the common conditions of research must be provided when that particular condition can be a distorting factor to the results obtained. In the given case, the two subjects groups were tested on two different times. There is a high chance that the morning group would have performed better than the afternoon ones.

Hence, it will be seen as a failure of the experimenter to test the groups in two different times.
