• longitudinal studies

• descriptive statistics

• cross-section studies

In which research method do we study one exceptional individual in depth and try to carefully draw conclusions about others based on the evidence?

• naturalistic observation

• hindsight bias

• experimentation

• case study

The American Psychological Association developed ethical principles urging investigators to

• avoid the use of monetary incentives in recruiting people to participate in research.

• forewarn potential research participants of the exact hypotheses that the research will test.

• avoid the manipulation of independent variables in research involving human participants.

• explain the research to the participants after the study has been completed.

When we see certain outcomes as obvious based on what has occurred, we may be experiencing

• empiricism

• hindsight bias

• critical thinking

• overconfidence

In order to learn about the political attitudes of all students enrolled at Arizona State University, Professor Marlow randomly selected 800 of these students to complete a questionnaire. In this instance, all the students enrolled at Arizona State University are considered to be a(n)

• correlation

• case study

Participants in an experiment are said to be blind if they are uninformed about

• the experimental hypothesis being tested.

• how the dependent variable is measured.

• which experimental treatment, if any, they are receiving.

Surveys indicate that people are much less likely to support “welfare” than “aid to the needy.” These somewhat paradoxical survey results best illustrate the importance of

• random sampling.

• the placebo effect.

• wording effects.

• naturalistic observation.
