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.
