The only way to test a particular variable for sure is to leave all other variables constant, and if a change in ONE variable creates an overall change, then you know that that variable caused it. But if you change 2 variables, and something changes, you don't know which one changed it for sure. So, one variable at a time. A full experiment can test many variables, though. better just to test one variable at a time that way one knows that any changes observed are accounted for by that variable.
13 - 3 amples are: (a) A study with two levels of one variable and four levels of a second variable is referred to as having a 2 X 4 design. This 2 X 4 study would have 8 cells (groups). (b) A study with three levels of each variable is referred to as having a 3 X 3 design. This design would have 9 groups. (c) A study with three levels of one variable and four levels of a second variable is referred to as having a 3 X 4 design (12 groups). The only inherent limitation of designs with multiple independent variables is that it is a bit more complex than the one-way designs.
