reading, acting, thinking, negating

In this lab, Ashley and I first tested our acting, reading, thinking and negating times without an outside variable.

In order to test whether or not a variable had an affect on our acting, reading, thinking and negating times, we decided to do jumping jacks to see if our heart rates would increase. Both Ashley and Kendra did 30 jumping jacks. This is how our times changed:

We both discovered that our results did not have any significant changes between our original time and our time after we were exposed to the outside variable. Our hypothesis was that the jumping jacks would increase the blood flow in our bodies thus increasing our times, but in some cases it did the exact opposite. So this could mean that doing jumping jacks made us more tired than what we were when we came to lab today.
