Demonstration/Exploration tools
centlimexc95.xls (about 1MB)	A tool to investigate and visualize The connection between probability density function and cumulative distribution function. How a random sample population is determined by the underlying probability distribution. The distribution of sample means for a given population of values. The distribution of sample standard deviations for a given population of values.
modified GC.xls	A graphing calculator in EXCEL that allows you to choose how many points to plot. (Written by T. Bailiff and T. Haynie.)
histogram to density function.xls	A modification of the Bailiff-Haynie graphing calculator which allows to demonstrate the transition from a histogram (discrete data) to a density function (continuous data).
Data files
data1, data2, data3, data4, data5, data6, data7, data8	Each data file contains 200 random numbers in cells B101 to B300.
Data generators
expdata.xls	Generates 200 samples from an exponential distribution with given parameter.
unifdata.xls	Generates 200 samples from a uniform distribution on the interval from 0 to 11.
sampmeandist.xls	Early prototype of centlimexc95.xls; can be used to generate approximately normal data.
Self assessment
how well do you study math.xls	This self-assessment, implemented by Hilda Black, originally a questionnaire by Richard Manning Smith (from his book "Mastering Mathematics: How To Be A Great Math Student.") rates study habits based on questions asked to the student

 

An assessment tool
Item Analysis Template	This is a tool to perform item analysis on test scores. Sample sets of test data are given.
BAP IV talk	These are power point slides for a talk on item analysis at the Best Assessment Processes IV conference at Rose-Hulman in April 2001.
