Confidence interval online calculators

Index

One mean Online calculator of confidence intervals of one mean: the asymptotic approximation when the sample size is LARGE, the Chebyshev's largest confidence interval, and the exact confidence intervals of exponentially or normally distributed variables.
 
One proportion Online calculator of the exact confidence interval of a proportion (i.e. Bernoulli / binomial distribution).
 
One SD Online calculator of the confidence interval of the standard deviation of a normally distributed variable.
 
One correlation Online calculator of the confidence interval of the Pearson's correlation between two normally distributed variables.
