Project 46: Chi Square GOF Highest Contribution
Intro Problem: Expected COUNTS for school distribution:
9th Grade: 63
10th Grade: 54
11th Grade: 36
12th Grade: 27
Actual COUNTS for school distribution:
9th graders: 60
10th graders: 50
11th graders: 40
12th graders: 30
Explanation:
Contributions:
(60-63)^2/63 = .143
(50-54)^2/54 = .296
(40-36)^2/36 = .444
(30-27)^2/27 = .333
The Chi Square test statistic is .143 + .296 + .444 + .333 = 1.22 but the category that contributed the most to this value was 11th graders with a contribution of .444.
Project 46: The variables 'expected' and 'counts' have been initialized.
'expected' represents the expected counts ([63, 54, 36, 27] in the example above)
'counts' represents the actual counts observed ([60, 50, 40, 30] in the example above)
Task: Appropriately initialize the values of 'big' which represents the value of the highest contribution to the chi square value (.444 in the example given)
