Frequently Asked Questions
A chi-square test is a statistical test used to determine if there is a significant difference between observed and expected frequencies in one or more categories.
If the p-value is less than your significance level (e.g., 0.05), you reject the null hypothesis, indicating a significant difference.
χ² = Σ((O-E)²/E), where O is observed frequency and E is expected frequency.
