The number of awards earned by students at one high school is recorded. Predictors of the number of awards earned include the type of program in which the student was enrolled (e.g., vocational, general or academic) and the score on their final exam in math. Below is a description of the variables and their levels of measurement Variables Student ID - NOMINAL Math Scores - RATIO Total # of awards - DISCRETE Program Type - NOMINAL (categorical with three levels: (1)general, (2)academic, (3)vocational) Total Students= 200 Total Awards = 194 Total math scores = 10529 Program Type sum = 405 Summarize in words the frequency distribution for the program type variable.
