Tests and Other Procedures




Distributions and parameters included in version 1.0.

In this case the sample is assumed to come from a certain statistical distribution with an unknown parameter. The intention is to perform a test or calculate a confidence interval for the parameter. The p-value and the width of the confidence interval is then calculated using the appropriate summary statistics. The following distributions and parameters are available.


  • Normal distribution
    • Means (standard deviation known)
    • Means (standard deviation unknown)
    • Standard deviation (mean known)
    • Standard deviation (mean unknown)
  • Lognormal distribution
    • Median (shape known)
    • Median (shape unknown)
  • Exponential distribution
    • Location (scale known)
    • Scale (Location known)
    • Scale (Location unknown)
  • Binomial distribution
    • Proportion
    • Odds
  • Hypergeometric distribution
    • Proportion
  • Poisson distribution
    • Mean
    • Hazard rate
  • Finite population
    • Population mean
    • Population proportion
  • Bivariate normal distribution
    • Mean 2 -Mean 1
    • Standard deviation 2 / Standard deviation 1
    • Correlation coefficient
    • Regression coefficient
