Sum of the square of the x values: ∑x2

R3

Sum of the y values: ∑y

R4

Sum of the square of the y values: ∑y2

R5

Sum of the multiplication of x and y: ∑xy

R6

Clearing the statistical registers before entering new data is necessary. Do this by touching

b

 

∑+

(also resets block registers and the display screen).

One-variable statistical calculations contain only x-values (data points). To enter only x-values, enter the value, and then touch ∑+.

Two variable statistical calculations contain both x and y values (data pairs). To enter these:

¾Enter x value

¾Touch ENTER

¾Enter y value

¾Touch ∑+

Every time ∑+ is touched, the calculator will:

¾Increase the value in R1 by one, and display the value

¾Add the x value to the number in R2

¾Add the square of the x value to R3

¾Add the y value to R4

¾Add the square of the y value to R5

¾Add the product of both x and y values to R6

The values stored in the b registers can be retrieved by touching RCL and entering the number of the storage register.

Recovering Incorrectly Entered Statistical Data

The accumulated statistics can be modified if entered incorrectly.

Steps:

¾Enter incorrect x and/or y values
