It was a much better day this Wednesday because I made a lot of progress with the experiment and presentation. Karen and Andy helped me a lot with data analysis on Excel. Also, my dad helped me make the movies work on a Mac, so I added them to my presentation. It was very busy all day, but I learned about a T-test, degrees of freedom, standard error, standard deviation, and more statistics stuff. Still stressed, but I'm feeling a bit better now that I have some information to put on the presentation. Yay!
