Question

If a researcher has two IV's that each are measured at the nominal level (e. g., gender and year in university study) and a DV that is measured at the interval or ratio level, what is the general name of this kind of design?

Answer 1

The study design using two nominal-level IVs and an interval/ratio-level DV is known as Factorial Design, allowing the study of interaction effects between independent variables.

Step-by-step explanation:

When a researcher is using two independent variables (IVs) that are measured at the nominal scale level, such as gender and year in university study, and one dependent variable (DV) measured at the interval or ratio level, the general name for this type of study design is Factorial Design. In factorial designs, each level of an independent variable is combined with each level of the other independent variables to observe the effect on the dependent variable. This method allows researchers to study the interaction effects between the independent variables on the dependent variable.
