How to report Chi-Square test results in APA style using software output

📚 Quick Study Guide

• 🔍 The Chi-Square test examines the association between two categorical variables.
• 💡 APA style requires specific formatting for reporting the test statistic, degrees of freedom, sample size, and p-value.
• 📝 The general format is: $\chi^2(df, N = sample\ size) = test\ statistic, p = p-value$.
• 📊 $df$ (degrees of freedom) is calculated as $(number\ of\ rows - 1) * (number\ of\ columns - 1)$.
• 🧪 Ensure your p-value is correctly reported (e.g., $p < .001$ if the software output shows $.000$).
