3. Nacisnąć przyciski [QUIT] [1], wybrać program „STAT” i nacisnąć przycisk
[ENTER].
● Program poprosi o wprowadzenie liczby pozycji i następnie o wprowadzenie
statystyk z dwiema zmiennymi (W = waga).
● W przypadku, gdy dane wykazują prawie liniową zależność, współczynnik
korelacji r leży blisko 1 lub –1, wartości te reprezentują prostą.
