Example: 1. Weight of AA batteries a. Problem: The variability in weight of randomly selected Energizer© AA batteries b. Variable: The weight of a single Energizer© AA battery c. Gather data: Weight randomly selected Energizer© AA batteries (one by one) using a scale with a readability of at least 0.1 grams (uncertainty +/- 0.05 grams) d. Evaluate: Check for assumptions (such as normality). Calculate the mean and standard deviation. Calculate confidence intervals. e. Conclusion: According to the data… the average weight… a minimum of 14.3 grams… f. Recommendations: (1) To make sure the data complies with the assumptions I should have… (2) Using a scale with a readability of 0.01 grams, due to… (3) Improve the randomness of battery’s selection, because there was problems with… (4) …
