What information can we draw from this factorial design notation - 2 x 3 x 3Group of answer choicesThe design has 18 independent variablesInteractions will existThe design as 2 independent variables, 3 dependent variables and 3 interacting variablesThe design has 18 conditions
Solution
The factorial design notation 2 x 3 x 3 indicates that there are three independent variables in the experiment. The numbers represent the levels of each variable. So, there are 2 levels of the first variable, 3 levels of the second variable, and 3 levels of the third variable.
The total number of conditions in the experiment is the product of the levels of each variable. In this case, 233 equals 18 conditions.
This design does not tell us directly about the existence of interactions, but in a factorial design, it is possible to test for interactions between variables.
Therefore, the correct answer is "The design has 18 conditions".
