Ukusebenzisa Indlela Yokubala
Ukubalwa Kokubuyela (SD, REG*)

Standard Deviation (SD) (Ukuhluka Okuvamile)
Sebenzisa ukhiye we- ukufaka imode ye-SD uma ufuna ukwenza
izibalo zokubala usebenzisa ukuphambuka okujwayelekile.
(SD)
• Kuyi-SD Mode ne-REG Mode, le nkinobho isebenza njengale
nkinobho.
• fx-82MS/fx-85MS/fx-300MS/fx-350MS: Qala njalo ngokufaka u-
(CLR) (Scl) ukususa imemori yestathistiksi.
fx-220 PLUS: Qala njalo ngokufaka u- (Scl) ukusula imemori
yestathistiksi.
• Idatha yokufaka usebenzisa ukulandelana kwesihluthulelo okuboniswe
ngezansi.
