Negative Binomial Distribution Table
Negative binomial distribution probability table for calculating probabilities of achieving r successes.
Poisson Distribution Table
Poisson distribution probability table with cumulative and individual probabilities for various lambda (λ) values.
t-Table (Student's t Distribution)
Complete t-distribution table with critical values for various degrees of freedom and significance levels. Essential for t-tests.
Z-Table (Standard Normal Table)
Complete z-table showing cumulative probabilities for the standard normal distribution. Find z-scores and probabilities.
How to Use Statistical Tables
Statistical tables are essential reference tools for hypothesis testing, confidence interval construction, and probability calculations. Before statistical software became widespread, these tables were the primary method for finding critical values and probabilities.
Common Statistical Tables
- Z-Table (Standard Normal) - Used for large sample hypothesis tests and confidence intervals
- t-Table (Student's t) - Essential for small sample inference about means
- Chi-Square Table - Used for goodness-of-fit tests and tests of independence
- F-Distribution Table - Required for ANOVA and comparing variances
- Binomial Table - Probabilities for binary outcome experiments
- Poisson Table - Probabilities for count data and rare events
When to Use Each Table
Choosing the correct statistical table depends on your data type, sample size, and the hypothesis being tested. Our guides with each table explain when and how to use them effectively.
