WebJan 27, 2024 · To calculate the chi-squared statistic, take the difference between a pair of observed (O) and expected values (E), square the difference, and divide that squared difference by the expected value. Repeat this process for all cells in your contingency table and sum those values. The resulting value is χ 2. WebAug 10, 2024 · In statistics, when you test a hypothesis about a population, you find a p-value and use your test statistic to decide whether to reject the null hypothesis, H 0. A p …

WebVideo transcript. We want to test the hypothesis that more than 30% of U.S. households have internet access with a significance level of 5%. We collect a sample of 150 households, and find that 57 have access. So to do our hypothesis test, let's just establish our null hypothesis and our alternative hypothesis. WebIf you get a large f value, it means something is significant, while a small p value means all your results are significant. The F statistic just compares the joint effect of all the variables together. To put it simply, reject the null hypothesis only if …
