There are three ways to compute a P value from a contingency table. Fisher's test is the best choice as it always gives the exact P value, while the chi-square test Are the groups different by random chance? The Chi-Square Test o helps us decide. Perhaps this? http://faculty.vassar.edu/lowry/newcs.html. perform a chi-square analysis [the logic and computational details of chi-square tests are described in Chapter 8 of Concepts and Applications];: calculate Cramer's V, which is a measure of the strength of association among the levels of the row and column variables [for a 2x2 table, Cramer's V is equal to the absolute value of the phi coefficient]; This unit will calculate the value of chi-square for a one-dimensional "goodness of fit" test, for up to 8 mutually exclusive categories labeled A through H. To enter an observed cell frequency, click the cursor into the appropriate cell, then type in the value. Expected values can be entered as either frequencies or proportions. Chi-Square to P Calculator. For values of df between 1 and 20, inclusive, this section will calculate the proportion of the relevant sampling distribution that falls to the right of a particular value of chi-square. To proceed, enter the values of chi-square and df in the designated cells and click «Calculate».

Welcome to the VassarStats website, which I hope you will find to be a useful and user-friendly tool for performing statistical computation. Each of the links in white text in the panel on the left will show an annotated list of the statistical procedures available under that rubric. Comparison of proportions free online statistical calculator. Computational notes. MedCalc uses the "N-1" Chi-squared test as recommended by Campbell (2007) and Richardson (2011). A Chi-Square Test calculator for a 2x2 table. Chi Square Calculator for 2x2. This simple chi-square calculator tests for association between two categorical variables - for example, sex (males and females) and smoking habit (smoker and non-smoker). Easy Fisher Exact Test Calculator. This is a Fisher exact test calculator for a 2 x 2 contingency table. The Fisher exact test tends to be employed instead of Pearson's chi-square test when sample sizes are small. MedCalc uses the "N-1" Chi-squared test as recommended by Campbell (2007) and Richardson (2011). The confidence interval is calculated according to the recommended method given by Altman et al. (2000). Literature. Comparison of proportions free online statistical calculator. Critical Chi-Square Values Calculator. Some more information about critical values for the Chi-Square distribution probability: Critical values are points at the tail(s) of a certain distribution so that the area under the curve for those points to the tails is equal to the given value of \(\alpha\).For a two-tailed case, the critical values correspond to two points on the left and right The logic and computational details of the Chi-Square and Fisher tests are described in Chapter 8 and Subchapter 8a, respectively, of Concepts and Applications Chi square test calculator vassar. A briefer account of the Fisher test will be found toward the bottom of this page. Chi square test calculator vassar
You are about to enter your data for a chi-square contingency table analysis. For this to make sense you should have a table of data (at least 2x2; maximum: 9x9).

To proceed, enter the values of chi-square and df in the designated cells and click «Calculate». For intermediate values of n, the chi-square and Fisher tests will both be performed. To proceed, enter the values of X 0 Y 1, X 1 Y 1, etc., into the designated cells. When all four cell values have been entered, click the «Calculate» button. To perform a new analysis with a new set of data, click the «Reset» button. Chi-Square Test Calculator. This is a easy chi-square calculator for a contingency table that has up to five rows and five columns (for alternative chi-square calculators, see the column to your right). The calculation takes three steps, allowing you to see how the chi-square statistic is calculated.

This calculator compares observed and expected frequencies with the chi-square test. Read an example with explanation . Note that the chi-square test is more commonly used in a very different situation -- to analyze a contingency table. This is appropriate when you wish to compare two or more groups, and the outcome variable is categorical.
