Multiple Choice

Which of the following best describes the logic used in the Before-After with Control Group experimental design that allows this to be a true experimental design?

• A) The experimental group change (O₂ - O₁) contains the change in the independent variable due to a.) the dependent variable and b.) extraneous variables. When we subtract from this the control group (O₄ - O₃), which is the change due to the extraneous variables, we are left with the change due solely to the dependent variable.
• B) The experimental group change (O₂ - O₁) contains the change in the complex variable due to a.) the dependent variable and b.) extraneous variables. When we subtract from this the control group (O₄ - O₃), which is the change due to the extraneous variables, we are left with the change due solely to the complex variable.
• C) The experimental group change (O₂ - O₁) contains the change in the dependent variable due to a.) the dependent variable and b.) extraneous variables. When we subtract from this the control group (O₄ - O₃), which is the change due to the extraneous variables, we are left with the change in the dependent variable due solely to the independent variable.
• D) The control group change (O₂ - O₁) contains the change in the independent variable due to a.) the dependent variable and b.) extraneous variables. When we subtract from this the experimental group (O₄ - O₃), which is the change due to the extraneous variables, we are left with the change due solely to the dependent variable.
• E) The experimental group change (O₂ - O₁) contains the change in the dependent variable due to a.) the dependent variable and b.). ..extraneous variables. When we subtract from this the control group (O4 - O3), which is the change due to the extraneous variables, we are left with the change due solely to the dependent variable.
