Introduction

The Floor Plan

People Trying Cookies:

The question we are trying to answer is:

"Will someone like a cookie better if they are told its homemade?"

We chose this topic because we genuinely enjoy cookies and just wanted to make some because they are delicious. We think that people will rate the homemade cookies higher because if they are told that we made them because they will feel guilty in how they answer and give us a biased answer of a higher rating to be polite.

How We Obtained Our Data

1 2 3 4 5 6 7 8 9 10

Conclusion

With our batch of solely homemade cookies, we put half of the batch in a Tupperware container and the other half in a box from a grocery store. We obtained our subjects by numbering the tables 1-30, and by using a random generator we picked the 8 tables we would be testing. Then by drawing a letter out of a hat the tables would be assigned to either the "homemade" or "store bought" cookies and rate them on a scale of 1-10. After receiving this data, we made a dot plot comparing the two groups.

Our research had proven our hypothesis because our average for homemade is 8.93 and "store bought" is 7.36. A mistake that we made was not having a equal number of people in both groups, but since the sample was random, in a way that we randomly chose tables, we did not know how many people would be at each table. Some tables had 2 people while others had 6, so it was not our fault that the two graphs have unequal amounts. One way to improve the accuracy of our study would be to increase the number of people we had in our study.
