In a Multilevel Modeling Design Investigating the Effects of Geographic

Multiple Choice

In a multilevel modeling design investigating the effects of geographic location, political orientation, and whether respondents attended public or private high schools, on attitudes toward proposed environmental regulations, the observed ICC (i.e., intraclass correlation) was .95. This value suggests that:

A) the researchers can probably assume that people from a given geographic location differed substantially and systematically from those in other locations; therefore, the nesting element of the design should not be ignored
B) the researchers can probably assume that people from a given geographic location did not differ substantially and systematically from those in other location; therefore, they could ignore the nesting element of the design
C) there is considerable error present between at least one predictor and the criterion
D) none of the above
