Group N
Collaborative Method 35
Lecture Method 35
Computer-Assisted Method 35

At the end of the experiment which lasted for 10 weeks, all subjects were tested on their mathematics performance and the scores were compared. Research Methodin Education

  1. Why do you think the researcher selected a quasi-experimental design and not a true design?
  2. State TWO (2) null hypotheses for the study.
  3. Discuss FOUR (4) threats to the internal validity of the experiment.
  4. Explain any TWO (2) techniques that the researcher could use to ensure the three groups are equivalent in ability.
  5. In order to reject the null hypothesis, it is necessary to analyse the data statistically. Explain.


Part C (10%) – 3 pages
