lab 9

wow, i definitely learned a great deal during the course of this lab! first of all, i had to learn how to perform linear regression equations all over again. i had to perform similar equations during high school while working with graphing, but it had been awhile. i learned that calculating all of those things could be tedious and time-consuming. also, i learned that excel really does make data manipulation and data analysis much easier than doing it by hand. once i had completed the first exercise, i was able to move through the second application rather quickly. excel is a wonderful tool once you learn how to use it properly.
