Chi square table round yellow

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. WebStep 3: Apply the chi-squared formula. The formula used to calculate a statistical value for the chi-squared test is as follows: Where: ∑ = Sum ; O = Observed frequency ; E = Expected frequency. These calculations can be broken down for each phenotype and added to the table to make the final summation easier.
