"FALSE"

"TRUE" or "FALSE"? A correlation of .00 between two variables indicates a perfect negative relationship.

"FALSE"

"TRUE" or "FALSE"? A correlation of .00 between two variables indicates a perfect positive relationship.

"FALSE"

"TRUE" or "FALSE"? A correlation of .00 between two variables indicates a relationship of unknown degree.

"TRUE"

"TRUE" or "FALSE"? A correlation of .00 between two variables indicates independence (no association) between the variables.

"TRUE"

"TRUE" or "FALSE"? A correlational technique frequently used in the construction of an instrument (such as an attitude inventory) that statistically groups test items that seem to be measuring a particular dimension or trait is called factor analysis.

"FALSE"

"TRUE" or "FALSE"? A correlational technique frequently used in the construction of an instrument (such as an attitude inventory) that statistically groups test items that seem to be measuring a particular dimension or trait is called multiple regression.

"FALSE"

"TRUE" or "FALSE"? A correlational technique frequently used in the construction of an instrument (such as an attitude inventory) that statistically groups test items that seem to be measuring a particular dimension or trait is called path analysis.

"TRUE"

"TRUE" or "FALSE"? For a predicted score of 30 and a standard error of estimate of 6, the chances are 95 out of 100 that the true score will be between 18 and 42.

"FALSE"

"TRUE" or "FALSE"? If there is a correlation of .80 between a test of scholastic aptitude and performance on an achievement test, one can infer that 80% of the achievement test variance is caused by scholastic aptitude.

"TRUE"

"TRUE" or "FALSE"? If there is a correlation of .80 between a test of scholastic aptitude and performance on an achievement test, one can infer that no causation can be inferred.

"FALSE"

"TRUE" or "FALSE"? If two measures have a high positive correlation and a person has a low score on one measure, his or her score on the other measure is most likely to be dependent on whether one variable is the cause of the other.

"TRUE"

"TRUE" or "FALSE"? If two measures have a high positive correlation and a person has a low score on one measure, his or her score on the other measure is most likely to be low.

"FALSE"

"TRUE" or "FALSE"? In multiple regression, one is able to predict one criterion from one predictor.

"TRUE"

"TRUE" or "FALSE"? In multiple regression, one is able to predict one criterion from two or more predictors.

"FALSE"

"TRUE" or "FALSE"? In multiple regression, one is able to predict two or more criteria from one predictor.

"FALSE"

"TRUE" or "FALSE"? In multiple regression, one is able to predict two or more criteria from two or more predictors.

correlation

"TRUE" or "FALSE"? Prediction studies use which of the following as the basic analysis technique?

"TRUE"

"TRUE" or "FALSE"? When a researcher decides that an appropriate analysis for a research model is to evaluate how several variables might influence two other variables that in turn influence the outcome variable of interest, the appropriate statistical analysis is LISREL.

"FALSE"

"TRUE" or "FALSE"? When a researcher decides that an appropriate analysis for a research model is to evaluate how several variables might influence two other variables that in turn influence the outcome variable of interest, the appropriate statistical analysis is canonical correlation.

"FALSE"

"TRUE" or "FALSE"? When a researcher decides that an appropriate analysis for a research model is to evaluate how several variables might influence two other variables that in turn influence the outcome variable of interest, the appropriate statistical analysis is factor analysis.

"FALSE"

"TRUE" or "FALSE"? When a researcher decides that an appropriate analysis for a research model is to evaluate how several variables might influence two other variables that in turn influence the outcome variable of interest, the appropriate statistical analysis is multiple regression.

"FALSE"

A correlational technique frequently used in the construction of an instrument (such as an attitude inventory) that statistically groups test items that seem to be measuring a particular dimension or trait is called Spearman r.

49%

A researcher finds a correlation of .70 between popularity ratings and self-concept scores. What percentage of common association can be inferred between the two variables?

test B

Four skills tests are tried as predictors of success in a tennis class. Each test correlates with later success as follows: test A, r = .27; test B, r = -.90; test C, r = -.40; test D, r = .65. The test that will most accurately predict success is __________.
