significantly lower values than that of experiment 1. However, while the results of Sample Bappear to match class values, the results of Sample A do not. The results show that the rawunpasteurized milk has less cells per mL than sample B, the fresh pasteurized milk, which doesnot line up with Experiment 1 and with the discussion surrounding it. Raw milk should havemore cells than the pasteurized milk, simply from the idea that the pasteurization process killsbacteria. The result from Sample A should be considered an error, but it is notable that severalother class results reported no growth from Sample A. It is possible that there was an error inincubation that affected all these samples, such as an over or under exposure of heat. Thebacteria may not have been at a suitable temperature to grow, or too much heat may have killedsome of the bacteria. Other possible sources of error could lie in the performance of preparingthe pour plate, such as mis preparing the dilution or mis labeling the agar plates. As thedifference between each dilution is substantial and many dilutions were found to have no growth,this could explain the low values
