Multiple regression, path analysis, hierarchical linear modeling, and structural equation modeling are similar in that all of them
a incorporate multiple criterion variables into their equations
b involve the analysis of relationships among three or more variables
c. do not rely on theory to determine which variables should be measured
d. all of the above.
To determine the correlation between a dichotomous criterion variable and set of predictor variables, which test would be most appropriate?
a. Canonical correlation
b. Logistical regression
c. Multiple linear regression
d. Factor analysis
obj. 8) An important reason for making a scattergram is that it
a. provides a test of the statistical significance of the obtained correlation coefficient
b. provides a measure of the confidence limits for the obtained correlation coefficient
c. is helpful for detecting nonlinear relationships
d. estimates the amount of shrinkage in a correlation coefficient when cross-validated.
A scattergram provides a visual representation of
a. the causal relationship between two measured variables
b. the standard error of measurement for two measured variables
c. a positive or negative relationship between two measured variables
d. the results of a path analysis.
