SOLUTIONS RATED A+
✔✔This is a type of quasi-experimental design that involves a comparison group that
was not developed on the basis of random assignment. It is called a ___________
control group design - ✔✔Non-equivalent
✔✔Experiments possess a high degree of internal validity because randomization of
different groups enables the researcher to rule out competing explanations.
True or False - ✔✔True
✔✔The generalizability of the research findings to other settings or samples is called
the:
A Internal validity
B External validity
C Genuine validity
D Generalizable validity - ✔✔External validity
✔✔The study's external validity is influence by:
A The adequacy of the sampling design
B Reactions of subjects to the novelty of the treatment
C The enthusiasm of the participants regarding the independent variable
D All of the above - ✔✔ALL OF THE ABOVE
✔✔The experimental treatment is the independent variable.
True or False - ✔✔True

threat.
True or False - ✔✔False
✔✔The threat of mortality stems from differential attritions from groups.
True or False - ✔✔True
✔✔If there is no constancy of conditions in a study, history becomes a potential threat
to the external validity of the study.
True or False - ✔✔False

same population. - ✔✔sampling error
✔✔The main criterion for evaluating a sample in a quantitative study -
✔✔representativeness
✔✔A convenience sample from a strata of the population - ✔✔quota
