Hi! I am new to the board. I sure wish I had found this at the beginning of the summer....I am in the last week of my internship, and I need to finalize the analysis of a bunch of data.
Here's the scoop:
I have been cycle testing scissors. What we're looking to do is compare data from the first cut vs data from the last cut (which may be after 2,500 - 10,000 cycles). Testing is done via a machine, so it is consistant. Also, we would like to compare data from one pair of scissors to another (ie US made vs identical model made in China).
The data: the force to cut paper is measured, then plotted (in Excel) via the machine controller.
I have only taken 1 semester of Stats, so I'm not exactly sure what to do here. So far, I have toyed with the following----paired t-test, and ANOVA single factor. Keep in mind, the only tool I have for analysis is the Data Analysis Toolpak in Excel.
I'll try and attach an Excel file.
Does anyone have any suggestions??? It would be of great help!!
