My EPPP Statistics and Research Design

Alpha (α) represents the significance level in hypothesis testing—the probability of committing a Type I error by rejecting a true null hypothesis. Commonly set at 0.05 or 0.01, it defines the threshold for statistical significance in research. The chi-square test is a nonparametric statistical method used to assess the association between categorical variables. The single-sample version compares observed frequencies to expected frequencies, while the multiple-sample version evaluates relationships across two or more variables.
