Exploring Measurement in the Food Industry
Our task for this lab was to collect mass information about various bags of Cheetos and use our data to determine the accuracy and precision of the bags. The purpose of this lab was to answer the guiding question, "Do you get what you pay for?". In this lab we used accuracy and precision to determine whether or not you get your money's worth when buying a small bag of Cheetos. On the packaging the bag states it's net weight is 28.3 grams. We used four different Cheetos bags to gather information. The first step was to find accuracy. Accuracy is defined as the net weight of 28.3g +/- .10g. We weighed the full bags of Cheetos separately and recorded the results, this is the gross weight. We then emptied the contents of the bags and weighed the packaging and recorded those results, this is the tare weight. After finding the gross and tare weight we then subtracted the tare weight from the gross weight and found our difference. The results are below. (G= Gross, T=Tare, D=
