Exam 9: Principles of Research Design and Statistical Preliminaries for Analyzing Bivariate Relationships

Comparing the relationship happiness and owning a pet is _____.

Which of the following does not apply to a within-subjects design?

One potential problem with between-subjects designs is the fact that the treatment in the first condition may have carry-over effects that influence performance in the second condition.

The ability to make a causal inference between two variables is a function of the statistical techniques one uses,not the research design used to generate the data that are analyzed by those statistical techniques.

Experimental strategies automatically control for confounding variables.

Random assignment of subjects to experimental conditions is only feasible when an investigator is using ____.

Statistics that allow you to evaluate your data and generalize to the population are called_____.

Explain the difference between Confounding variables and disturbance variables.

Comparing the time it takes to develop a solution to a problem,in subjects given a study guide before the problem is given compared with those not given a study guide is _____.

A(n)_________ strategy is where a set of procedures or manipulations is performed to created different values of the independent variable for the research participants;while a(n)__________ strategy involves measuring differences in values that naturally exist in the research participants.

A common strategy to control disturbance variables is (are):

A _____ variable is one that is unrelated to the independent variable but that affects the dependent variable.

Statisticians can determine the effects of violating assumptions by using _____ or performing _____.

It is entirely possible for two variables to be _____ one another,but for no _____ relationship to exist between them.

Which procedure is not used to control for confounding variables?

In an experimental strategy,a set of procedures or manipulations is performed in order to create different values of the dependent variable for the research participants.

A problem with holding a variable,such as gender,constant is that

Nonparametric statistics require quantitative dependent variables and are usually applied when these variables are measured on a level that at least approximates interval characteristics.

What are the most common criticism and general disadvantage attributed to experimental designs?

Since random assignment cannot be applied to experimental groups,experimental variables will always be confounded with all other variables that are naturally related to them.
