Since the p-value (0.01697) is less than our alpha level of 0.05, we reject the null hypothesis of our test. We have sufficient evidence to say that our results are statistically significant at alpha level 0.05.
WebFeb 8, 2024 · For a chi-square test, a p-value that is less than or equal to the .05 significance level indicates that the observed values are different to the expected values. Thus, low p-values (p< .05) indicate a likely difference between the theoretical population and the … WebApr 25, 2024 · Chi-squared, more properly known as Pearson's chi-square test, is a means of statistically evaluating data.
