Reading Habits

Part A (15%) – 4 pages

A researcher conducted a study to determine the effectiveness of the Collaborative Method, Lecture Method and Computer-Assisted Method in teaching mathematics to 16-year old students in a secondary school. She used a quasi-experimental design for her study and selected sample and divided them into three groups as shown in the table below.

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.

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 B (10%) – 3 pages

A Survey on Internet Usage among the People of Micronesia

Micronesia is an island with a population of 120,000 people and one-third are between 18 and 30 years of age. You have been given the task to find out about internet usage among 18 to 30- year olds. Due to time and financial constraints, you are able to access to only 1% of the population.

[Note: You have to decide what is meant by ‘reading habits and interests’]

1. Explain how you intend to select the sample to ensure it is representative of the population.

2. Suggest FIVE research questions for the study.

3. Name FIVE demographic variables you would include in your study.

4. Besides the demographic variables write down TEN Questions you would include in the questionnaire.

5. Explain why you have chosen these TEN questions.
