In a study that employs a 2 x 6 x 9 design, the number of independent variables is determined by the number of factors represented in the design notation. Each number in the notation corresponds to a different independent variable (factor), with the values indicating the number of levels each variable operates at in the study.

In this case, there are three factors indicated: one with 2 levels, another with 6 levels, and a third with 9 levels. Since there are three different factors present, the correct understanding is that the study is examining three independent variables. This tells us how many different influences might affect the outcome of the research, allowing for a comprehensive analysis of the effects of these variables on the dependent variable.
