Discriminant Analysis
Part1. Using Green and Salkind (version 7e), Lesson 35, complete exercises 1 – 8.
Conduct a discriminate analysis to distinguish research scientists from teaching professor monguls.
• Include the output that includes the research scientist group mean number of publications; grant money
univariate ANOVA F statistic
• the discriminant function c2.
• Identify the correctly classified percentage of research scientists;
• the overall correctly classified professor monguls and research scientists.
• Identify the predictor variables that contribute the most to discriminating between the professor monguls and
research scientists.
• Create a combined groups plot that displays the classification of the two groups.
The data for Exercises 6 through 8 are in the data file named lesson 35 Exercise File 2
Conduct a discriminate analysis to determine if both discriminate functions should be interpreted. Be sure to
show your results.
• Interpret the discriminant function or functions.
• Write a results section based on your analysis in APA style.
Part 2. In two or three paragraphs, explain what the Box’s M, the canonical correlation, the Chi-square,
standardized canonical discriminant function coefficients, structure matrix, and the classification statistics mean
and how they are interpreted.
Sample Solution
As mentioned earlier, incidental teaching is a procedure is reinforcing because the child initiates the intervention based on their own interest, and receives the reinforce when the child attempts to follow the instructor’s prompt. Incidental teaching is also an intervention that promotes lasting and impactful results because it is an intervention that is early, it also can be done in a variety of settings with different people, it can have family involvement, the procedure can include peers, and it is fun for the child since it initiated by the child (McGee et al., 1999). Since it is child selected, it drives the child’s motivation, which ultimately assists the child to learn.
