Chi square goodness of fit p value calculator
WebWe see that the calculated value of the Chi-squared goodness of fit statistic is 27.306905068684152 and its p-value is 4.9704641133403614e-05 which is much smaller than alpha=0.05. Thus we conclude that Null Hypothesis H0 that NUMBIDS is Poisson distributed can be resolutely REJECTED at 95% (indeed even at 9.99%) confidence level. WebTo calculate the test statistic for a goodness-of-fit test follow the following steps: you will end up using the formula [latex]\frac{(O-E)^2}{E}[/latex] over and over. Step 1: Pick one …
