Document Summary

Note: the graded components will be submitted via crowdmark. Submit graphs in pdf format, everything else in pdf or jpg format. Refer to the dental gold data set posted on our courselink website. This data set is a subset of a larger experiment; we are using data from only one of the two alloys originally included in the experiment. Our data set will be used to analyze the effects of three factors (method, Temperature, and dentist) on the hardness of dental fillings. Each of five dentists prepared the gold alloy by each of the three methods of condensation and at each of the three temperatures used in the molting process (temperatures in ef). The dentist prepared a filling in an artificial substrate from each alloy made, and the hardness was measured via the vickers hardness test. Note the resulting data set contains 45 observations, one for each treatment combination.
