My Scientific Question: Does adding Standard Deviation to your averages help you get to your conclusions?
What I did: I collected all my data from my experiments and averaged them out. For time:Concentration #1 had an average for about 19 seconds. Concentration #2 had an average for about 18 seconds. And Concentration #3 had an average for about 14 seconds. So you can pretty much see the decreasing of the averages. And For size: Concentration #1 had an average 4.5 cm. Concentration #2 had an average 2.7 cm. And for Concentration #3 had an average for about 3.1 cm. You can tell that there was no trend. The averages were all over the place.
What I found: From my data, I found out that the averages for concentrations of time decreased. And for the averages of size went all over the place. When I added standered deviation (the amount of variation of a set of data values) to my averages of size and time, it changed. It showed that the averages of time and size kind of are the same because of the range of numbers or variability that we had. I also found that variability is really important in this project because because it shows you the errors that you had and would make you think of what t change next time you do this experiment.
