2.When psychologists conduct a study, a            sample gives every member of the population an equal chance of being selected.

3.In inferential statistics,            means that the differences observed between two groups are large enough that it is highly unlikely that those differences are merely due to chance.

4.When psychological researchers use the correlational method to study variables, a correlation coefficient indicates the       between two variables.

5.

A                 design is a special kind of systematic observation, used by correlational researchers, that involves obtaining measures of the variables of interest in multiple waves over time.

6.When psychologists conduct a study, the group of participants chosen for the study is referred to as the:

7.In the context of research settings, researchers who use        attempt to view behavior without disturbing the environment.

8.In a   , neither the participants nor the experimenter administering the treatment are aware of which participants belong to the experimental group and which are part of the control group.

9. Albert, a student researcher, varies the amount of food given to rats in an experiment, to measure the effect on their learning behavior. In Albert's study, the amount of food given is the                                            variable.

10.Participants in an experimental research study listen to a lecture either in a lecture hall filled with natural light or in a lecture hall with no windows and artificial light. Before leaving the lecture halls, the participants fill out a mood survey. What is the independent variable in this study?

11.In the context of a correlational study, what does the positive or negative sign of a correlation coefficient indicate?
