Threats to validity of Research Design

Threats to validity include: Selection--groups selected may actually be disparate prior to any treatment.. Mortality--the differences between O 1 and O 2 may be because of the drop-out rate of subjects from a specific experimental group, which would cause the groups to be unequal.. Others--Interaction of selection and maturation and interaction of selection and the experimental variable.

Threats to validity of Research Design

Cronbach (1982) is opposed to this notion. He argued that if a treatment is expected to be relevant to a broader context, the causal inference must go beyond the specific conditions. If the study lacks generalizability, then the so-called internally valid causal effect is useless to decision makers.
