WebAug 6, 2024 · To find the F critical value in R, you can use the qf () function, which uses the following syntax: qf (p, df1, df2. lower.tail=TRUE) where: p: The significance level to use. df1: The numerator degrees of freedom. df2: The denominator degrees of freedom. lower.tail: If TRUE, the probability to the left of p in the F distribution is returned. WebΧ 2 = 8.41 + 8.67 + 11.6 + 5.4 = 34.08. Step 3: Find the critical chi-square value. Since there are four groups (round and yellow, round and green, wrinkled and yellow, wrinkled and green), there are three degrees of freedom.. For a test of significance at α = .05 and df = 3, the Χ 2 critical value is 7.82.. Step 4: Compare the chi-square value to the critical value
