Below you will find four hypotheses. Each hypothesis is simply a statement that could be supported or not
supported by evidence. Choose one hypothesis from the list and design an experiment (not a descriptive or
correlational study) that could test that hypothesis. Then, answer the questions below about your experiment.
Be sure that each answer is in a complete sentence and is grammatically correct.
Possible Hypotheses
People in noisy environments are more likely to suffer from high blood pressure and anxiety.
If adults are told that an infant is named “John,” they are more likely to see “him” as bigger and stronger than if
the same infant is called “Joan.”
People in a bar will be more likely to leave the bartender tips if the tip jar already has some money in it.
Students who chew gum during a test do better than those who do not.
Answer the following questions about your experiment:
What hypothesis did you choose?
Identify your independent variable and describe how you will manipulate the variable (e.g. which participants
will be receiving this variable)
Identify your dependent variable and describe how you will measure it
Name 1 possible confounding variable you need to be aware of in your experiment. How will you minimize or
eliminate the confound?
