Statistically determinate formula
WebMay 23, 2024 · The chi-square formula Both of Pearson’s chi-square tests use the same formula to calculate the test statistic, chi-square (Χ 2 ): Where: Χ 2 is the chi-square test statistic Σ is the summation operator (it means “take the sum of”) O is the observed frequency E is the expected frequency WebIn most studies, a p-value of 0.05 or less is considered statistically significant — but you can set the threshold higher. A higher p-value of over 0.05 means variation is less likely, while a lower value below 0.05 suggests differences. You can calculate the difference using this formula: (1 - p-value)*100.
