normalCDF & InvNorm on TI-84 Plus Calculator: Normal Calculations

Показать описание

We calculate areas on the standard normal curve and use areas to find cutoff values (z-scores). We do our calculations on a TI-84 Plus using the normalCDF & InvNorm functions.

Fellow Stats students, the Casio Fx-CG50 lets you input the "Tail" in a LEFT, RIGHT, or CENTRAL position into its Inverse Norm function, giving you BOTH left and right values in ONE computation -
Ex:
Tail: Central,
Area: .7
Std Dev: 3.5
Mean: 200, Execute...
"X1 Inv = 196.3724"; "X2 Inv = 203.6275
Highly recommended!
