closed ended; open ended

______ can be used to counter order effects.

counterbalancing

When a question on a survey is actually two questions in one this is called a ______ question.

double-barreled

Manipulation of an independent variable in a study increases/decreases the internal validity of the study.

increases

When the effect of one independent variable depends on the levels of another independent variable, this is called a(n) ______.

interaction effect

Main effects compare ______ means and interaction effects compare ______ means.

level; condition

An experiment conducted with one or a few participants to better understand the behavior of those individuals is called a small ______ design.

n

When a variable that is not of interest in a study may explain the results of a study is a ______.

third variable problem

Describe what an experiment is

Participants are randomly assigned to conditions (levels of the IV). The effect each level of the IV has on the DV is assessed.

Explain the main advantage of a factorial design over a single- factor experiment.

Researcher can be more efficient in testing the effects of multiple independent variables in one experiment and can also examine the effects of the interactions of those independent variables on the dependent variable.

Provide an example of a correlational design.

[Describes a relationship between 2 continuous variables]

Suppose that a researcher found that as introversion (as measured on a standardized questionnaire) of participants goes up, the number of social activities attended per week goes down. This finding represents what kind of relationship?

negative relationship

The inferential statistic used to assess correlational research designs.

pearson r

"Do ACT scores indicate future academic performance?" is an example of a predictive/descriptive question?

predictive

In a correlational study, the variable that is used to predict the outcome variable is called the ______ variable.

predictor

The development and validation of surveys are called ________.

psychometrics

Define testing effects.

when participants are tested more than once in a study with early testing affecting later testing

Participants receive all levels of a(n) ______ variable, but only one level of a(n) ______ variable in an experimental design.
