Chi square test for trend. The chi squared test for trend test for a linear trend against the null hypothesis of no trend. In effect this is equivalent to a linear regression (see Unit 12) of proportion infected against score, weighted according to the number of individuals with each score. Chi-Square Calculator. The results are in! And the groups have different numbers. But is that just random chance? Or have you found something significant? The Chi-Square Test gives us a "p" value to help us decide. Chi-squared with degrees of freedom and P-value. The Chi-squared statistic is the sum of the squares of the differences of observed and expected frequency divided by the expected frequency for every cell: For a 2x2 table, MedCalc uses the "N−1" Chi-squared test as recommended by Campbell (2007) and Richardson (2011). The chi-square test of independence is used to test the null hypothesis that the frequency within cells is what would be expected, given these marginal Ns. The chi-square test of goodness of fit is used to test the hypothesis that the total sample N is distributed evenly among all levels of the relevant factor. Instructions: This calculator conducts a Chi-Square test of independence. Please first indicate the number of columns and rows for the cross tabulation. Then type the table data, the significance level, and optionally the name of rows and columns, and the results of the Chi-Square test will be presented for you below:

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. The Chi Square for Trend function calculates the odds ratio, chi square for linear trend, and p-value statistics based on the response to an exposure score and whether the patient has become ill. The exposure score is a measured outcome from a study that states the level of exposure the patient received.
