A researcher investigates whether there is a relationship between hours of sleep and memory for photographs. The researcher assigned 40 participants to sleep in the laboratory and woke 20 of the participants after 4 hours of sleep and the other 20 after 8 hours of sleep.

Answer:

It is the experimental condition.

Step-by-step explanation:

In the experiment given in the question, the amount of sleep is the independent variable and the number of photographs they remember is the dependent variable because it depends on the amount of sleep.

The 8 hours of sleep, which creates the difference in the experiment between the control group and the test group, is the experimental condition.

The experimental condition is the variable that is changed to let the researcher observe the effects on the dependent variable.
