Question: The dependent factor in this experiment is tensile strength of the wire. This is the outcome that the engineer is measuring and is influenced by the different levels of raw materials and temperatures. b. Main effect(s): In this experiment, there are two main effects: Material effect: Refers to the influence of the four different raw materials (1, 2, 3, and 4) on the tensile strength. Temperature effect: Refers to the influence of the three different temperatures (1, 2, and 3) on tensile strength. c. Interaction effect(s): The interaction effect in this scenario is: Material and Temperature interaction: This examines whether the effect of one factor (material) on tensile strength changes depending on the level of the other factor (temperature) and vice versa.
