Statistical Tables
Find the statistical table you need for a probability, critical value or hypothesis-test reference. Browse standard normal, Student's t, chi-square and F distribution tables, with clear examples and links to related calculators.
Z Table
Standard normal probabilities
Look up positive and negative z-scores, percentiles, tail probabilities and critical Z values.
Open Z Table →T Distribution Table
Find Student's t critical values by degrees of freedom and one- or two-tailed significance level.
Open table →Chi-Square Table
Find chi-square critical values by degrees of freedom and upper- or lower-tail probability.
Open table →F Distribution Table
Find F critical values using numerator and denominator degrees of freedom.
Open table →Pearson R Critical Values
Compare an observed correlation with a critical absolute r value for a chosen sample size.
Open table →Z-Transform Table
Find discrete-time transform pairs, inverse sequences, properties and regions of convergence—not standard normal probabilities.
Open table →Fourier Transform Table
Search continuous-time pairs, inverse transforms and properties in angular frequency or Hz.
Open table →Laplace Transform Table
Find unilateral pairs, inverse transforms, initial-value properties and convergence conditions.
Open table →Binomial Distribution Table
Explore an interactive binomial distribution table for exact and cumulative probabilities. Choose n and p, highlight values, and follow worked examples.
Open table →Poisson Distribution Table
Use an interactive Poisson distribution table for exact and cumulative probabilities. Select lambda and event count, highlight values, and see examples.
Open table →Derivative Table
Find common derivatives in a searchable table with power, trig, logarithmic, exponential, and inverse function formulas, rules, and examples.
Open table →Integral Table
Browse a searchable table of integrals with standard antiderivatives, trig and exponential formulas, conditions, and step-by-step examples.

A probability lookup starts with a statistic and finds an area under its distribution. A critical-value lookup starts with a tail probability and finds the cutoff. Choose the convention required by your statistical procedure.
