 * == **__Goals:__** ==
 * The goal of this project was to test the difference between two-dimensional and three-dimensional vision; and in testing determine the difference in 2 dimensional accuracy when comparing a participants dominant, and non-dominant eye. Another goal was to prove the hypothesis correct in stating that "When using two eyes (3D) the person will be more likely to accomplish the task at hand (catch a tennis ball). The reason this was hypothesized is that it is scientifically proven that using two eyes gives a person a 3 dimensional view, while only one leaves us with a 2 dimensional picture; and it is pretty clear that 3D is more helpful than 2D is.


 * == __**Discoveries:**__ ==
 * In this experiment I learned that the percentage of success rate (catching the tennis ball) gap between 2D vision (Dominant eye) and 3D vision (Both eyes) was not nearly as significant as I had predicted. 91% of throws were caught with 3D vision, while 90% were caught using the dominant eye, and the non-dominant eye was not far behind with a total of 86% of throws caught. This was surprising because I thought the percentage difference would be double-digit, and it ended up only being 1% difference. The hypothesis is still correct, and from this I will take that 3D vision gives you the best shot at completing tasks that involve vision, but using just your dominant eye is not almost as productive.


 * == ** __Challenges and Solutions:__ ** ==
 * There were two main challenges that I faced while working on this experiment. The first involved the results of data and how they didnt match my exact predictions, and the other was questionable, and that was whether the number of people I tested wasnt enough, and whether that had swayed the percentage in the end. ﻿ ﻿ For the conclusion of the project it occurred to me that I had 20 participants so the percentages would be very easy to calculate thus solidifying the number of people I tested to be enough. And when I compared the data i collected to other predictions and studies I saw that while ther was barely a difference in the numbers the point was still proven and had been close to what had been previously observed.


 * == __** Looking Back: **__ ==
 * While I was content with the outcome of my project and the data I collected; looking back there are a few things I would do differently. I would have collected more data by testing a larger base of people, and done more research to find out why there was not a more significant difference in the dominant-eye, and both eyes. I also would have gone deeper into how the brain ties into your ability to control your hands while doing certain tasks. With that reasearch I would have had a more complete understanding of the brain and the eyes and how they make it possible to accomplish things.


 * == __** 5 Things I Wish I Knew: **__ ==
 * #1: Try to stick as close as you can to your original plan, whether its the plan, the procedure, or anythig else that you have written early on, the closer you follow it, the better prepared you'll be closer to the end, and the easier it will be for you.
 * #2: Plan as much as you can up front and dont let things fall into place as you go along becasue it could turn up sloppy, and you might be left with some loose ends when you're finished with your project.
 * #3: While making your topic interesting and learning as much as possible, try not to add too many variable becasue that may make the project as a whole a lot less deep becasue you have too many things to touch upon, and you might not have enough time to spend equal time on all the different parts.
 * #4: Spread out the work and make sure you dont try to do most of the project close to the day its due because the work will be lower quality, and you will probably get a significanlty lower grade than you would have had you not procrastinated.
 * #5: Do something that interests you, and not necessarily something that you think would get you a good grade. Becasue if you're more into your project you'll be more inclined to want to work on it, and therfore do more, do it better, and get a better grade.
