Statistical Calculations

SD REG

Standard Deviation SD

Use the F key to enter the SD Mode when you want to perform statistical calculations using standard deviation.

SD ........................................................................................... F F 1

•Always start data input with A B1(Scl) <to clear statistical memory.

•Input data using the key sequence shown below. <x-data> S

•Input data is used to calculate values for n, Σx, Σx2, o, σn and σn-1, which you can recall using the key operations noted nearby.

To recall this type of value:	Perform this key operation:
Σx2	A U1
Σx	A U2
n	A U3
o	A X1
σn	A X2
σn–1	A X3
