The Simple Experiment

1. If we want to know if a therapy works, we would use

the experimental method
the non-experimental method

2. The control group receives

no treatment
the treatment

3. The hypothesis that the drug has no effect on behavior is

an experimental hypothesis
a null hypothesis

4. We can accept the null hypothesis


5. To have a simple experiment, you must

conduct the study in a laboratory
randomly assign participants to condition

6. If the results are statistically significant, they

are probably due to chance alone
are probably NOT due to chance alone

7. If the results are statistically significant, then the treatment probably

does have an effect.
does NOT have an effect.

8. If the results are not statistically significant, then

you can conclude that the treatment has no effect.
you cannot conclude anything.
