Q2. A social psychologist attempts to understand the effect of two different teaching methods on a group of students to facilitate better results in examinations. A single class of students is taught by Teacher A in a fast-paced manner, only to be followed by slow-paced teaching by Teacher B after a few days. This procedure of single-subject experimentation signifies that:

  • This type of experimentation gives control over variability in the sample.
  • Inferential statistics can be easily employed in such studies.
  • The findings originating here are generalizable to other students as well.
  • It is impossible in situations like these to understand the effect to different variables.

Q5. An organization was willing to understand the effect of modification in the work schedule in a group of factory workers. A second factory was taken as the control group for comparison. The experiment was of a nonequivalent-control-group design because the workers were not randomly allocated to the two groups.

However, the experimental factory group showed a significant increase in performance and the control group lacked such improvement in output. These patterns signify that:

  • The control group and experimental groups were incomparable to begin with
