About the TI-86 and TI-89 Programs


When executing any of the discrete distribution programs, you can obtain a complete distribution by entering 1 when asked.

To view this distribution on the TI-86, press LIST, then EDIT (F4). Under xStat, the range of the random variable is listed. Adjacent under yStat, the pdf values P(X = k) are listed. Adjacent under fStat, the cumulative distribution values P(X <= k) are listed. The Binomial and Poisson programs also adjust the WINDOW and STAT PLOT settings for a scatterplot of the pdf (xStat vs. yStat).


To view the complete distribution on the TI-89, press APPS, then 6 for Data/Matrix Editor, then 1 for Current. Under c1, the range of the random variable is listed. Adjacent under c2, the pdf values P(X = k) are listed. Adjacent under c3, the cumulative distribution values P(X <= k) are listed. The Binomial and Poisson programs also adjust the WINDOW and STAT PLOT settings for a scatterplot of the pdf (c1 vs. c2).
