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.
