The following example is a facet of a study encountered in research on attribution theory (e.g., Weiner, 1974). Subjects were randomly assigned to perform a task under either a Success or a Failure condition. That is, subjects under the former condition met with success while performing the task, whereas those under the latter condition met with failure. Subsequently, the subjects were asked to rate the degree to which their performance was due to their ability and to the difficulty of the task in which they engaged. Following are data (illustrative), where higher ratings indicate greater attribution to ability and to task difficulty.

(a) Do a multiple regression analysis, regressing the treabnents, represented as a dummy variable, on the two dependent variables. I use a miniature example so that you may do all the calculations by hand. You may find it useful to analyze the data also by computer and to

(b) Do a discriminant analysis of the same data. compare the output with your hand calculations. Compare the results with those you obtained under (a). Interpret the results.
