A one-way between-subjects ANOVA is appropriate for this study as it involves comparing the means of a single independent variable (years in college/freshman, sophomore, junior, or senior) on a dependent variable (class grades). This design assumes that each group of participants (freshman, sophomore, etc.) is distinct and there is no overlap between them. A two-independent sample t test would compare the means of two independent groups, while a two-way between-subjects ANOVA would involve two independent variables and their interaction on a dependent variable.
