The Solomon Four-Group Experimental Design is specifically designed to assess the effect of pretesting on posttesting, by using two groups that receive a pretest and two groups that do not receive a pretest. It is not primarily designed to assess statistical regression. While it is straightforward to implement, it can be more complex than other designs due to the need for multiple groups. Therefore, statement A is not true.
