The three TI83/84 features dealing with normal distributions and how they are (or could be) used.Normalcdf is the normal (Gaussian) cumulative distribution function on the TI 83/TI 84 calculator. If a random variable is normally distributed, you can use the normalcdf command to find the probability that the variable will fall into a certain interval that you supply. Where is NormalCDF on the Calculator?Inverse Normal Distribution on a TI-83 or TI-84 Calculator. Youā€™re most likely to encounter the term ā€œinverse normal distributionā€ on a TI-83 or TI-84 calculator, which uses the following function to find the z-critical value that corresponds to a certain probability: invNorm(probability, Ī¼, Ļƒ) where: probability: the significance levelProbabilities are calculated using technology.
