Quizplus · Accepted Answer

The graph shows two factors (F1F1F1S1 and F1F1F10) with four levels each, indicating a 2x4 factorial design. The presence of interaction is suggested by the nonparallel lines, where the effect of one factor depends on the level of the other factor. Therefore, the correct choice is option B, which represents a 2 F1F1F1S1F1F1F10 4 factorial design with interaction.
