A one-way within-groups ANOVA would be appropriate for this research because the researcher is examining differences in academic performance within the same group of athletes across three different time periods (preseason, active competitive season, and postseason). It is a within-groups analysis because the same group of athletes is being measured at each time point. A one-way between-groups ANOVA would be inappropriate because the researcher is not comparing separate groups of athletes, but rather the same group at different time points. Paired-samples t tests and independent-samples t tests would also be inappropriate because they are not designed for analyzing multiple time points within the same group.
