Subgroup comparisons are done by:
a) dividing cases into the appropriate subgroups, describing each subgroup in terms of a given variable, and comparing those descriptions across subgroups.
b) dividing, describing, and comparing subgroups on independent and dependent variables.
c) analyzing the simultaneous relationships among several variables among subgroups.

You are helping code one of your professor's data. You are coding occupation and notice that there is no code for a respondent's indicated occupation. Which of the following statements would not be incorrect in relating the problem to the professor?
a) The coding scheme for occupation is not mutually exclusive
b) The lack of a code for this particular occupation signals a mismatch between the data and the coding schem.
c) The coding scheme for occupation is not exhaustive.
d) The coding scheme is not a good scheme.
e) All of these choices would be correct statements.

Certain guidelines should be kept in mind when coding. Among these is (are) the following:
a) the coding scheme should be appropriate to the analysis intended in the study.
b) the coding scheme should be appropriate to the theoretical concepts being examined.
c) the reliability of the coder(s) should always be verified.
d) code categories should be both mutually exclusive and exhaustive.
