To calculate effect size using eta squared, we need to divide SSS by SST (total sum of squares). SSS is given as SS_BG + SS_E = 320. To find SST, we need to add up the sums of squares for all sources of variation (between, within, and error). However, we are not given this information in the question, so we cannot calculate SST. Therefore, we cannot determine the effect size using eta squared.
