stats82.uue:  Statistic programs for TI-82. Some are pedagogical,

eg. demonstrate the Central Limit Theorem.  Others replace statistical

tables, do statistical graphing.

Program      Description

=======      ===========

ANOVA........Analysis of variance

BISHAPE......Graph binomial probability mass function

CDF......... Graph an empirical cumulative distribution function

CHI2.........Tail area under a chi-squared probability density function

CLT..........Demonstrate the Central Limit Theorem

CONT.........Illustrate a discrete distribution converging to a

             continuous distribution

CUMU.........Cumulative frequency or distribution

DISTMEAN.....Demonstrate sampling distribution of the mean

DISTS2.......Demonstrate sampling distribution of the sample variance

FCRIT........Critical value for the F distribution

FLIP.........Simulate flipping a coin.  The relative frequency

             converges to 1/2.  A plot is also given.

FREQHIST.....Set the window and generate a frequency histogram

GAMMA........Gamma function for half-integral values

LINES........Point-slope, interpolation, graph

LSCI.........Compute and graph least squares confidence intervals

NORMAL.......Find the area under a standard normal probability density

POSHAPE......Graph Poisson probability mass function

RANKSUM......Ranksum statistic

RCRIT........Critical value of Pearson-Moment Correlation, r

SRCORR.......Spearman rank correlation coefficient statistic

SRCRIT.......Critical value fo the the Spearman Rank Correlation Coefficient

TAREA........Area under the t-distribution

TMENU........Compute the critical value from a Student's t distribution

TSUB.........Subroutine called by TMENU

X2TTEST......X^2 test for equality among binomial probabilities,

             or the X^2 test of independence

X2MENU.......Finds the critical value for a chi-squared distribution

X2SUB........Subroutine for the X2MENU program

ZVAL.........z value from normal distribution
