2
SD mode
For standard deviation (SD mode) you can show
2 x̅ xσn xσn-1
1 2 3
1 = Arithmetic mean
2 = Population
3 = Sample
REG mode
For regression calculations (REG mode) you can show
2 x̅ xσn xσn-1
1 2 3
1 = (x̅): mean
2 = (xσn): population
3 = (xσn-1): sample
y̅ yσn yσn-1
1 2 3
1 = (y̅): mean
2 = (yσn): population
3 = (yσn-1): sample
In case of regression calculations other than quadratic regression it shows
A B r

1 = (A): Regression coefficient A (y-intercept)
2 = (B): Regression coefficient B (slope)
3 = (r): Correlation coefficient
