The design of the yogurt experiment is important in several key ways. One being the specific question the experiment is supposed to answer. Another type of factor would be any possible bias within the experiment and during the analysis of data. This experiment did foresee any of the experimental design issues possible. In order for someone to replicate this experiment it would be important for them to use all the same tools and brand of the experiment. It would also be important for safe handling and cleanup and understand the possible variables in temperature and lighting. If other tried to replicate this experiment it could determine the experiment is valid only if all procedure and handling were exactly the
