Lab Assignments for Cornell University Math 1710

Generally lab assignments will be performed during recitation on Thursdays and written up to be turned in the following Thursday.

Please understand that the lab time is for doing the software part of the assignment. You should work together to create the graphs, run the stats analysis, etc, cutting and pasting results into a layout or Word document. You can print the layout or create a pdf and email any files to yourself or put them on a USB flash drive. Later on at home you can write up your answers to the rest of the questions individually to be handed in. Answers may be handwritten directly on a printout of your layout if convenient.

Caution:

When you save a file to your removable media and especially when you go to attach to an eMail, be sure the file is closed!
Safest is to Quit and Save from DataDesk, your word processor, or your PDF reader then work with the file.
Sad stories abound of people who sent themselves an eMail with an attachment having 0 Bytes because the file was open when they sent the eMail.

"Describing a Distribution on your Labs:" Pages 49-56 of Chapter 4 give a quick introduction to shape, center, and spread. Together with unusual features, this is what you should report when asked to describe a distribution or histogram. We'll study this in greater detail later.
