Data Analysis & GraphsData analysis

◦ Follow the steps from the packet we used in class to complete a full data analysis in excel.

◦ Don’t forget the t-test!

Graphs◦ Create one

histogram to compare the curves for each experimental group

◦ Create one line graph to show the various rates of reaction for each experimental group

◦ Make sure to label all axes and include a key for each!
