ApplicationSince we know the only dependent test was between mood and lunch (the p-value 0.0017 is less than alpha, 0.05, so its significant), we can observe how our friends might act based on their lunch time. Bias and ErrorCategoriesHad to group them so we didnt have so many categories that we couldnt compare themExample: if someone said stressed or apathetic, we considered them unhappyExample: bands and phrases were included in brandBy D lunch, we knew our categories & told the people we surveyed, so they had more narrow options Bias and Error ContinuedFriends often influenced others at their tables when saying moodOr, if didnt know us, may have felt uncomfortable being honestAlso, our own friends affects mood and willingness and goofinessShould have just done one person per table? Too difficult to get good sample sizeDidnt record people who didnt want to respond could have made that a separate option for mood, maybeShirt color if more than one shirt or predominant colorShirt designif more than one design or cardigans, layers, etc. Bias and Error ContinuedOnly surveyed people on one dayOnly surveyed teens 10th- 12th grade (no adults)Only surveyed in school different even if with different lunchtimes at work or other schools?Personal Opinions/ ConclusionsSurprised mood really doesnt affect shirt color from what our data tells usCould have made surveying more accurateDifferent/ wider populationDifferent way to survey PapersWebsite but thatd result in voluntary biasPull people aside to avoid friend influence awkward and intimidating?Question and Answer
