The first thing that is likely to occur to these researchers is to obtain a sample of middle-school students who have been bullied and then to measure their self-esteem.Science and the Scientific MethodThe first group is the experimental group. This group is the group that has the factor that is being tested (Experimental Variable). It is easy to identify the experimental variable, since it is usually stated in the hypothesis. The second group is the control group. The control group is identical to the experimental group in every way, except that

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 …
