Which of the following about the word-association and sentence-completion methods is
FALSE?

the coding problems of unstructured methods.

Which of the following is FALSE?
a. A multivariate problem of analysis obtains whenever the analyst has two or more
measures per sample object and he wishes to analyze the variables together.

dependent variable.
e. In interdependence analysis, all of the variables have equal footing in the sense none
