We followed the principles of a well designed experiment well. We used repetition when we did multiple trials to see the change in mass of the toilet paper. I learned that it is important to do multiple trials because you can have an outlier which will affect your data if it is not corrected with other trials. We used blocking when we looked at how ply count would affect absorbency. We used the controls effectively because we used the same brand of milk for all trials and left all conditions the same except for the ones we were trying to manipulate.
The most important thing that I learned through this was understanding that it takes a while to design a good experiment and you must consider many factors.
