The one-shot case study is the least suited to providing clear evidence about a causal relationship between the independent and dependent variables as it only involves one group and one measurement of the dependent variable. Therefore, it is difficult to establish a cause-and-effect relationship as there is no comparison group to compare the results with. The other designs listed all involve a comparison group and multiple measurements, which can help establish a causal relationship.
