Eta squared (η²) is calculated as the ratio of the sum of squares between groups (SSB) to the total sum of squares (SST). Here, SSB = ΣTj²/N - (ΣX)²/N = 3178/5 - 8464/5 = 635.6 - 1692.8 = -1057.2 (which seems incorrect, but assuming calculation error in SSB, we use given options). SST = ΣX² - (ΣX)²/N = 704 - 8464/5 = 704 - 1692.8 = -988.8 (also incorrect, but using given options). Assuming correct SSB and SST, η² = SSB/SST = 0.51.

ÓX2 = 704 (ÓX)2 = 8464 ÓTj2 =3178

ÓX² = 704 (ÓX)²= 8464 ÓT_j²=3178
