Examine the following results reported in a quantitative study:
 
"The scores varied for band members (M=3.5), choir members (M=3.9), and for student athletes (M=5.4) for attitudes toward engaging in school activities during the 3-5 p.m. period of time.  A comparison of the groups, at an alpha of .05, showed a statistically significant difference among the three groups, F(3,8)=9.87, p = 0.031, effect size = 0.91 SD."
