Exam 17: Partial Correlation and Multiple Regression and Correlation

To the extent that the variables do not meet the assumptions of regression analysis,coefficients and slopes become

In the multiple regression equation,the partial slopes are represented by the symbol

When examining a bivariate relationship using Pearson's r,the partial correlation computed while using one control variable is called

To investigate the combined effects of several independent variables on a single dependent variable,we use

In the multiple regression equation,the partial slopes are analogous to

In the analysis of the relationship between crime,poverty,age,and region reported in the text,which independent variable(s)had the strongest effect on the dependent variable according to the beta-weights?

The coefficient of multiple determination (R²),with two independent variables,is

While unstandardized partial slopes permit predictions of Y in the original units of the variable,standardized partial slopes permit an assessment of

A researcher examines the relationship between poverty and crime rates for 100 metropolitan areas and finds a zero-order correlation of 0.37.She controls for the percent of families that are headed by single parents and finds a first order partial correlation of 0.33.This is a ____ relationship.

Partial and multiple correlation are based on

In the least-squares multiple regression equation,the unstandardized partial slopes show

Partial correlation will detect all of the following relationships among variables except

After controlling for Z,the partial correlation coefficient between X and Y is the same value as the bivariate Pearson's r.This pattern would be taken as evidence of
