Instructions

  1. 1

    Slide the calculator out of the cover and initialise the calculator by pressing "Shift," "CLR," "3" and "Equals." This clears replay memory and variables.

  2. 2

    Enter the correct mode. Press "Mode" and "1" to enter Basic Arithmetic calculations called "COMP;" press "Mode" and "2" to perform Standard Deviation, called "SD;" press "Mode" and "3" to perform Regression calculations, called "REG." For this example, choose COMP.

  3. 3

    Perform a basic calculation. Calculate 12% of 1,500 by entering "1,500" on the numerical keypad, followed by the multiplication button and "12" on the numerical keypad. Then press "Shift" and the "%" button. The answer, 180, will show on the display.

  4. 4

    Press "Mode" and "2" to perform an SD (Standard Deviation) calculation. Start inputting data by pressing "Shift" "CLR," "1" and "Equals." This clears statistical memory.

  5. 5

    Calculate Sample Standard Deviation, Population Standard Deviation and Arithmetic Mean for a series of numbers. Enter "55" and the "M+" button -- in SD mode the "M+" key functions as the "DT" key. Keep entering numbers. Enter "51" and "DT," then "55" and "DT," then "53" and "DT; enter "DT" again to include 53 twice, enter "54" and "DT" and "52" and "DT."

  6. 6

    Press "Shift," "S-VAR," "3" and the "Equals" button to perform the Simple Standard Deviation calculation. The answer is 1.407885953. Press "Shift," "S-VAR," "2" and the "Equals" button to perform the Population Standard Deviation calculation. The answer should be 1.316956719. Calculate the Arithmetic Mean by pressing "Shift," "S-VAR," "1" and the "Equals" button. The answer will be 53.375.
