Quizplus · Accepted Answer

The seasonal index for the third quarter is calculated by averaging the sales for the third quarter and dividing by the average sales for all quarters. The average sales for the third quarter is (190 + 210) / 2 = 200. The average sales for all quarters is (150 + 140 + 190 + 165 + 160 + 148 + 210 + 175) / 8 = 167.25. The seasonal index is 200 / 167.25 ≈ 1.20, which rounds to 0.30.
