The Major disadvantage of the Static-Sample Comparison design when compared to t

Question

The Major disadvantage of the Static-Sample Comparison design when compared to true experimental designs in... Because the treatment is only given to one group, we can't determine its effect on the second group due to random differences in the two. Lack of random assignment to conditions means that we have no mathematical assurances that the two groups being compared are functionally equivalent to each other minus only random differences. The more samples you collect, the less sure you are that the differences found can be attributable to the treatment. Lack of random assignment to conditions means that we nave no assurances that the two groups being compared are functionally equivalent to each other.

Explanation / Answer

There is no formal way to determine whether the two groups would have been the same if it had not been for the treatment. If the treatment group and the comparison group differ after the treatment, this might be a reflection of differences in the initial recruitment to the groups or differential mortality in the experiment. Option D is correct.
