WebFeb 8, 2024 · Formula Calculation. Calculate the chi-square statistic (χ2) by completing the following steps: Calculate the expected frequencies and the observed frequencies. For each observed number in the table, subtract the corresponding expected number (O — E). Square the difference (O —E)². Divide the squares obtained for each cell in the table by ... WebProbability Value - Is the decimal value determined from the X2 table and is the probability of accepting the null hypothesis. A 0.05 probability value equates to a 95% confidence interval. The Chi-squared test formula is: Example: If we cross two pea plants that are heterozygous yellow pods, we would expect a 3:1 phenotypic ratio.

Now determine if your chi square value is a good fit with your data. Your degrees of freedom (df) is the number of possible phenotypes minus 1. In your case, 4 - 1 = 3. Find the number in that row that is closest to your chi square value. Circle that number. 5.
