Lab 7 : “Goodness Fit” the Fun way…ChiSquare Analysis
... “goodness of fit” test. This test allows us to determine if any differences between our observed measurements (counts of colors from our M&M sample) and our expected numbers (what Mars advertises to be true) are simply due to chance, sample error, or some other reason (i.e. Mars Co.’s sorters aren’t ...
