Two Correlation Coefficients
This calculator computes the p-value for comparing two correlation coefficients. Users input two correlation coefficients (R1,R2) and two sample sizes (N1,N2). The null hypothesis is that the... |

Binomial Proportions
This calculator computes the probability that two proportions are equal, given sample proportions. The user inputs values for x1, n1, x2, and n2. The null hypothesis is that the two proportions are... |

The Student T Test for One Sample
This calculator computes the t-statistic, degrees of freedom (DF), and p-value for the Student's t Test for pairwise differences. The user inputs either the pairs or the differences in the pairs. ... |

The Student T Distribution
This calculator computes probabilities from the student t distribution. The user inputs t and the degress of freedom, and P(|T|>=t) is returned at the top of the page. |

Chi-Square Test for Known Distributions
This test checks whether an observed distribution differs from an expected distribution. It computes the chi-square statistic, degrees of freedom (DoF), and p-value. Users input a table with row... |

IDEAL: Contingency Tables
This module demonstrates how to perform two chi-square tests, the chi-square test of independence and the chi-square test of homogeneity, through the use of contingency tables. The applets provided... |
