A.   situation in which several independent variables are highly correlated with each other.

B.   estimated regression coefficient that has been recalculated to have a mean of zero and a standard deviation of 1.

C.   statistical technique that analyzes the linear relationship between a dependent variable and multiple independent variables by estimating coefficients for the equation for a straight line.

D.   statistic that compares the amount of variation in the dependent measure "explained" or associated with the independent variables to the "unexplained" or error variance.

E.   statistical procedure that estimates regression equation coefficients that produce the lowest sum of squared differences between the actual and predicted values of a dependent variable.

A.   there is a weak association.

B.   a strong association is evident.

A.   A positive beta indicates that as the size of an independent variable decreases, the size of the dependent variable increases.

B.   It is an F-ratio that has been recalculated to have a mean of 1 and a standard deviation of 0.

C.   It ranges from 1.00 to 3.00 and is a positive correlation coefficient.

D.   It shows the change in the dependent variable for each unit change in the independent variable.

E.   It is an estimated correlation coefficient.

A.   the variables we want to analyze have a binomially distributed population.

B.   the variables have been measured using interval- or ratio-scaled measures.

C.   when the correlation coefficient is weak, there is a consistent, systematic relationship between the two variables of interest.

D.   the relationship we are trying to measure is curvilinear.

E.   when the correlation coefficient is strong and significant, the two variables of interest are associated in a curvilinear fashion.

A.   presence

B.   direction

C.   strength of association

D.   dispersion

E.   type

A.   TRUE

B.   FALSE

A.   The Pearson correlation coefficient measures the degree of linear association that ranges from 1.0 to 10.0.

B.   The larger the correlation coefficient, the weaker the association between two variables.

C.   The null hypothesis for the Pearson correlation coefficient states that there is always a strong association between two variables.

D.   The null hypothesis for the Pearson correlation coefficient states that the correlation coefficient is zero.

E.   The Pearson correlation coefficient measures the degree of linear association between three variables.

A.   simple regression.

B.   bivariate regression analysis.

C.   the Pearson correlation coefficient.

D.   the Spearman correlation coefficient.

E.   multiple regression analysis.

A.   tells you the percentage of the total variation in the independent variable caused by the dependent variable.

B.   ranges from -1.0 to +1.0.

C.   describes the variation in the dependent variable caused by the control variable.

D.   is a stronger measure than the Pearson correlation coefficient.

E.   ranges from .00 to 1.0.
