Included calculators are:

  • 2x2xn calculator with associated confidence intervals and statistical tests
  • Pair-matched case control 2x2 calculator with associated confidence intervals and statistical tests
  • Chi-square calculator for trend detection
  • Binomial calculator for determining the probability of an observed proportion
  • Poisson calculator for determining the probability of an observed number of successes
  • Sample size calculators
    • For unmatched case-control studies
    • For cohort studies
    • For population surveys
