This type of correlation is appropriate for quantitative variables that yield ratio and interval data such as GRE scores and GPA.
What is the Pearson Product Moment Correlation?
100
The relationship, or correlation, between two independent variables such as GPA and GRE scores.
What is collinearity?
100
A study in which the researcher tests the effect of two or more independent variables or factors.
What is a factorial design?
100
Factor analysis does this by combining variables that are correlated with each other.
What is reduce a large number of variables into a smaller number of distinct factors?
100
This method will only tell you if there is a relationship between years of practice experience and client satisfaction ratings.
What is correlation?
200
This type of correlation is appropriate for two variables when as least one variable is ordinal, such as class rankings.
What is Spearman Rho?
200
A regression involving a single independent variable.
What is simple regression?
200
The singular effect of an independent variable or factor on a dependent variable.
What is a main effect?
200
Correlations between the original variables and the factors.
What are factor loadings?
200
Use this method to determine if there is a relationship between getting and A or B in this class and your score on the licensing exam.
What is the Point Biserial correlation?
300
This type of correlation is used when one variable is a dichotomous categorical variables and the other is continuous and quantitative, yielding interval or ratio data.
What is the Point Biserial Correlation?
300
A regression involving multiple independent variables and a single dependent variable.
What is multiple regression?
300
The effect of two or more independent variables on the dependent variable.
What is the interaction effect?
300
These factors do not overlap or correlate with each other.
What are orthogonal factors?
300
Use this method to predict client progress in counseling based on client age, level of education and scores on a symptom checklist.
What is multiple regression?
400
A correlation coefficient tells you these two things about the relationship between two variables.
What are direction and magnitude?
400
The numerical value of any parameter estimate that is directly associated with the independent variables.
What is a regression coefficient?
400
An independent variable whose values will not be generalized beyond the experiment, such as gender defined as male and female.
What is a fixed factor?
400
These factors may correlate with each other.
What are oblique factors?
400
This method will help you determine what the principal factors are in a 100 item client survey of attitudes toward counseling.
What is factor analysis?
500
As one variable increases the other variable decreases.
What is a negative correlation?
500
Independence, normality, homoscedasticity, and linearity.
What are the statistical assumptions of regression?
500
A variable whose values will be generalized beyond the experiment.
What is a random factor?
500
Component analysis and common factor analysis.
What are the two fundamental models of factor analysis?
500
This method allows you to test the hypotheses:
1. Male clients over 40 years old will reported fewer depressive symptoms after a course of cognitive-behavioral therapy
2. Female clients under 40 years old will report fewer depressive symptons after a course of person-centered therapy.
