Many statistical tests (along with both frequentist and Bayesian methodologies) are based upon probability distributions. The following programs allow these to be investigated further:
'''NCSSCALC''' ''(Allows the investigation of various probability distributions, for example to estimate the probability of a particular outcome)'' http://www.ncss.com/download_probcalc.html
'''p-value''' [direct link to software] ''(Statistical utility program for computing p-values from probability distributions under standard hypothesis tests)'' http://www.vetschools.co.uk/EpiVetNet/files/pvalue10.zip
'''Tables''' ''(A programme containing 42 statistical distributions. For each, in addition to the percentage points and their inverses, there is an extensive help, a plot of the density, a mechanism for generating random values, and various descriptive statistics)'' http://www.bobwheeler.com/statistics/StatisticalTables/statisticaltables.html
'''BetaBuster''' ''(allows the parameterisation of Beta distributions based on the desired qualities of the distribution)'' http://www.epi.ucdavis.edu/diagnostictests/betabuster.html
