Practice questions 2 Flashcards
Consider the research study below, which refers to questions 3 and 4.
A researcher studies a group of children aged between 10-12 years from a school in West
Wales. The study is looking to see whether a new teaching method will have an effect on
academic performance. 50 students in the School are sampled for the study. The first 25
students to arrive in the school are allocated to the new teaching method and the last 25 to
the old teaching method.
Q3. Which of the following statements is true?
1. The study would be looking to test a theory.
2. The study population is all 10-12 year old children in West Wales
3. The study would be considered quasi-experimental rather than true experimental
- The study would be considered quasi-experimental rather than true experimental
The researcher does not have a theory about how the new teaching method will
affect academic performance.
The study population is the population from which the sample was chosen – in this
case the school.
This study cannot be a true experiment as control of all confounding variables would
be problematic.

Q4. Which of the following statements is true?
1. The sample is an example of random sampling, because the researcher has no
influence in who arrives in the school first or last.
2. The control group are students taking the old teaching method
3. Any generalisation to all children in West Wales would lack external validity.
- The control group are students taking the old teaching method
- Any generalisation to all children in West Wales would lack external validity.
Random sampling requires that all members of the population have a chance of being selected at each selection point. This method is not random and could lead to problems as there might be something very different about children that arrive early and those that arrive later.
