Question 8

Assume that you have developed a study technique that you believe will result in students scoring higher on research methods exams.You test your study technique with the design diagramed below.
Where: $ \quad R= $ random assignment
$ \mathrm{O}= $ observation on the dependent variable
$ \mathrm{X}= $ the independent variable
$ \begin{array}{llll}\mathrm{R} & \mathrm{O} 1 \mathrm{X} & \mathrm{O} 2\end{array} $
