Calculators:

In this course, you are required to use a scientific calculator on tests. Most people have one or more of these lying around the house. That will be fine to use. If you want to buy one, you should be able to find several acceptable ones for about $10 or less. I recommend that you get one with a two-line display and two-variable statistics. The advantage of a two-line display is that you can still see what you typed in after you see the result of the calculation. That makes it easier to find mistakes. The advantage of two-variable statistics is that you can use it to compute the correlation coefficient between two variables. You are NOT REQUIRED to get a calculator with a two-line display or that does two-variable statistcs.

Every calculator company I know about has several calculators like this. I am not listing them here. But it may be useful to see a picture, so here is such a picture: http://education.ti.com/educationportal/sites/US/productDetail/us_ti30x_iib.html

After you think you have figured out how to use your calculator, then use it to find the mean and standard deviation of these numbers: 3, 4, 6, 6, 9. Your answers should be: mean = 5.6 and standard deviation = 2.30217. Then write down some notes for yourself on how to use your calculator to do this so that you can look them up later if you forget. .
