12.4 Calculating the ANOVA F test P-value. For each of the following situations, find the degrees of freedom for the F statistic and then use Table E (or software) to approximate (obtain) the P-value. Five groups are being compared, with 5 observations per group. The value of the F statistic is 3.47. Four groups are being compared, with 11 observations per group. The value of the F statistic is 4.28. Five groups are being compared, with 65 total observations. The value of the F statistic is 2.97.

Step 1
For the first situation, we have 5 groups with 5 observations per group. To calculate the degrees of freedom for the F statistic, we need to find the degrees of freedom for the numerator and the denominator. The numerator degrees of freedom is equal to the number Show moreā¦

12.14 Calculating the ANOVA F test P-value. For each of the following situations, find the degrees of freedom for the F statistic and then use Table E to approximate the P-value. (a) Six groups are being compared with five observations per group. The value of the F statistic is 2.47. (b) Four groups are being compared with 11 observations per group. The value of the F statistic is 5.03. (c) Five groups are being compared using 65 total observations. The value of the F statistic is 3.11.
