CALCULATORS DURING EXAMS – SCHOOL POLICY!

Due to increasing challenges to academic integrity and fairness, the policy of this School is that where the course instructor permits the use of a calculator in a test or exam, the calculator must be an approved model.  The approved scientific calculators are Canon 502G,  Sharp EL510RB, and Casio FX260. These calculators have the statistical functions that you need.

In addition, the models approved for use in accounting examinations at Ryerson (models Royal XE24, Royal XE36, Royal XE48) are considered approved but students should be aware that they lack scientific functions. The use of any other calculator is not permitted unless specifically authorized by the instructor.

#### FINDING AND USING THE STATISTICAL FUNCTIONS ON YOUR CALCULATOR.

Most calculators carry some basic statistical functions, but you need to turn the calculator to statistical "mode" before you can access them.  You will need to consult the instruction manual (or find it below). In most cases try pressing the "MODE" key several times until the small "SD" appears in the window.  This means you are in stats. mode.  From there, you will be able to enter each observation using a key marked possibly SUM (Σ), and NOT the addition (+) key.  Every time you enter data the number of observations shows in the window, 1, 2, 3, etc.  After you have entered everything, you will be able to access the common statistical functions:  Σx,  Σx²,  N!,  S,  S²,  σ,  σ². and the mean (usually shown as x with a bar on the top such as:  but this does not always show because different computing operating systems use different codes for symbols).

For CASIO calculators, (most models) go to:

Statistical functions for some of the most common Casio types are covered on page 26 here:

And here are the instructions for the Casio F-260 (Thanks to Joanne Metcalfe!)

PLEASE LET ME HAVE ANY INFO YOU HAVE concerning YOUR calculator's statistical functions, so that I can post it here.
