Comparing subjects evaluated by a male experimenter with subjects evaluated by a female experimenter with respect to the number of tasks completed in one hour is _____.

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

If you have a small sample size what type of statistics should you use?

A ____ variable is related to the independent variable in a manner that renders interpretation of the relationship between the dependent variable and independent variable ambiguous.

The technique of matching to control for confounding in an experiment results in ____.

Which of the following variables would be an observed variable in all research strategies?

Jacob is studying the development of motor coordination in monkeys from birth to old age for his Master's thesis.However,he only has one year to collect his data.What type of design should he use?

An investigator was interested in determining if the size of a coin influenced judgments of numerosity when people were asked to make judgments of how many coins were in a pile of coins.Fifteen subjects were asked to estimate the number of pennies in a display of 43 coins.In another condition,15 different subjects estimated the number of dimes for the same display.In the above experiment,the size of the coin is also related to its value.Value is thus a ____.

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

Random assignment is possible with

Two important distributional assumptions are the _____ assumption and the _____ assumption.

In order to determine the correct statistical test to use for your experimental design there are 4 requirements.

A major goal of research design is to create alternative explanations.

A ____________________is unrelated to the independent variable but affects the dependent variable.

For many observational independent variables,only _____ designs are applicable.

The ____________________is a computer simulation which allows statisticians to determine if a data set violates an assumption.

A Monte Carlo study is a computer simulation study in which the statistician uses the computer to generate scores for hypothetical populations that he or she knows violates a distributional assumption in some way.

An experimental strategy is a set of procedures which creates different values of ____.

What are the relative strengths and weaknesses of between-subjects versus within-subjects designs?

For many observational independent variables,only between-subjects designs are applicable.
