S-VAR

Auf einem Casio Rechner kann man statistische Variablen aufrufen

SHIFT
		2

 

---

SD mode

For standard deviation (SD mode) you can show

SHIFT
		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

SHIFT
		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  2   3

1 = (A): Regression coefficient A (y-intercept)

2 = (B): Regression coefficient B (slope)

3 = (r): Correlation coefficient

x̂  ŷ          1  2

1 = (x̂)

2 = (ŷ)

 

In case of quadratic regression it shows

A  B   C     1  2   3

1 = (A): Regression coefficient A

2 = (B): Regression coefficient B

3 = (C): Regression coefficient C

x̂1  x̂2  ŷ    1   2   3

1 = (x̂1)

2 = (x̂2)

3 = (ŷ)
