These are some of my graphs...Don't worry - I understand that they need editing!

Sheet 1: is the graph of the average force? Can you put error bars on this? Sheet 2: I'm not sure what this means - can you explain? I wouldn't use the graph on sheet 3 - I don't think you need the number of grams since you have the force. What is sheet 4?

Sheet 1: Yes it is. I will definitely get the error bars on! Sheet 2: This is the graph for mass v. force. The graph needs work because last time, I couldn't get it to quite work... Sheet 3: This is grams per sample, so do you think I could use it? (considering that although the same force might have been applied to different samples, the mass of the samples were different...) Sheet 4 is the start of the elasticity data.

For now, do you mind looking over my paper (for background research)?

12:30 Sheet 4 - elasticity data - looks good. So, if I'm reading correctly, A was not significantly more elastic than B, but definitely more than C. B was significantly more elastic than C. Is that right? Do a graph of that. Is the unit in mm? Use error bars.

Sheet 3 - is it the number of grams that the sample weighed? If so, instead of doing the graph as written, maybe you should do an average force per gram of sample - that might be very interesting.

Sheet 2 - What are you trying to show on graph 2? That there was a direct relationship between the amount of mass applied and the amount of force that it took to break? If so, that might take some "special skills" on excel. I'll have to think about that. I haven't taken a look at your research paper yet. I'll do it now and get back to you.

1:17 - I just looked at your paper. I'm sending it back with some edits.

Do you mind checking the edit (specifically to the intro)? First paragraph looks much better! :) Don't forget to add a purpose to the beginning and a hypothesis to the end of this in order to make it a great introduction! Nice job.

Thank you! That gives me some more confidence! : ) As of right now, I guess I will leave out graph 2, since I don't quite know how to graph it...

Here is my powerpoint. I put the control in red so that I remember to edit. Would you consider the oil-based plastic to be the control?
