In a twoway factorial design there can be a one interaction

In a two-way factorial design, there can be

a) one interaction and one main effect

b) one interaction and two main effects

c) two interactions and one main effect

d) two interactions and two main effects

Solution

An interaction effect in a two-way factorial research design occurs when the influence of one variable changes according to the level of another variable. A two-way factorial design is “two-way” because the influence of two separate variables is being studied

[ANSWER] b) one interaction and two main effects
