Correlation
Type of correlation when one variable increases and one decreases.
What is negative correlation?
Simple equation for linear regression?
What is y=mx+b?
Indicated by more than one continuous IV.
What is multiple regression?
This type of hypothesis: The mean score for the test is 77.3
What is null hypothesis?
This type of independent variable is used in ANOVA tests.
What is a categorical variable?
We control for this in the case of partial correlation.
What is a third variable?
In a standard multiple regression, all IVs are entered ____ and their effects are measured as if the DV was entered after all of them;
What is simultaneously?
This how participants are controlled in a paired-samples t-test when there are two experimental conditions.
What is participants participate in both subjects?
What is repeated measures ANOVA?
This type of correlation is when there are two categories that are continuous.
What is Biserial Correlation?
Involves a single IV and a single DV. Can be predicted by a linear equation.
What is a simple linear regression?
Researchers determine the order in which the IVs are entered in this test.
What is hierarchical multiple regression?
This is the limitation with t-tests.
What is you cannot compare more than two groups?
This is the null hypothesis for a one-way ANOVA test.
What is there are no differences in the mean?
This distinguishes semi-partial correlation from partial correlation.
What is an effect on only one of the variables?
This is the range of the strength of a linear relationship.
What is -1 to 1?
In a stepwise multiple regression, researchers may want to control specific IVs from an array of predictors to determine if it has this kind of effect.
What is meaningful contribution?
You would use this when comparing 2 means from the same subject.
What is a paired samples t-test?
What is Spearman's Correlation Coefficient?
Difference between regression and correlation.
What is cause and effect?
This is the portion of DV that can be explained by the combination of IVs.
What is r2?
This test would be used for this type of question: What type of therapy will best reduce symptoms? (CBT, Psychodynamic)
What is independent t-test?
Tests that the variances of the differences between conditions are equal in a repeated measures ANOVA.
What is Mauchly's test?
