It is not the right thing to do because people do not have the right answer.It is just the waist of your time. effectiveness using the drug and a placebo. The experimental unit in this case will be the cake batter. A _________ variable is a variable that is related to the explanatory variable, and it also affects the response variable, making it difficult to determine which one of the two is really causing the response. Ensure that no important findings from your experiments are left out.
