A nutritionist is studying the effects of two different diets (Diet A and Diet B) and two exercise routines (Routine X and Routine Y) on weight loss in adults. Each participant is assigned to one diet and one exercise routine. What feature of this experimental design indicates that a two-way ANOVA is the appropriate statistical test?

Each participant's weight loss is classified by both diet and exercise routine, allowing analysis of both factors and their interaction.

The groups are not independent, so ANOVA is not suitable.

The outcome is not numerical, so ANOVA cannot be used.

Only one factor is being tested, so a one-way ANOVA is sufficient.
