The assumption of matching participants on important characteristics is not necessary for a two-way between-groups ANOVA. However, it can be beneficial in reducing variability and increasing the power of the analysis. The other assumptions listed (normality of population distributions, similar variability, and random selection of participants) are critical for accurate results in a two-way between-groups ANOVA.
