A researcher introduces a new mathematics program in one school district and uses a neighboring district as a no-treatment contr
ol group. After the program is in place for 6 months, the researcher intends to give the students in both districts a standardized mathematics test and then compare their scores. This research cannot be classified as a true experiment because the researcher does not control the assignment of participants to groups and therefore has a nonequivalent groups design.
Answer:The researcher does not control the assignment of participants to groups and therefore has a nonequivalent groups design.
Explanation: The research design described above is a Quasiexperimental research, which is very similar to an experimental research with one very noticeable difference. In a quasi experimental research, such as described above, groups employed are usually preexisting, meaning that the experimenter does not control or have any impact on assigning subjects into the different groups, The group design are used just as they have preexisted, The nonequivalence portrayed in the group design of quasi experiment usually result in low internal validity expected of an experimental research.

Preponderance of the Evidence is the burden of proof that applies in civil cases. This has to do with the weight of evidence, more convincing evidence and its probable truth or accuracy and not the quantity of evidence in deciding on a civil case.
