Research methods quiz

Question 1

Study A A researcher is predicting a relationship between the consumption of sweets and tooth decay in children.

Study B A researcher is exploring a patient’s experience of living with persistent pain.

Study C A researcher predicts that increasing measures of alcohol will result in increasing reaction times to stimuli.

1) Study A would be hypothesis testing, but the research design would not be experimental.
2) Study B is likely to generate qualitative data.
3) Study C would be hypothesis testing, and the research design would be experimental.

Answer 1

1,2 and 3 correct.

Question 2

Study A A researcher is predicting a relationship between the consumption of sweets and tooth decay in children.

Study B A researcher is exploring a patient’s experience of living with persistent pain.

Study C A researcher predicts that increasing measures of alcohol will result in increasing reaction times to stimuli.

Which one is correct
1) The dependent variable in study C would be an objective measure of time.
2) The dependent variable in study A would be the consumption of sweets.
3) Study B is a theory testing research study.

Answer 2

Number 1 only is correct

Question 3

Which one is correct
1) Qualitative research is more about theory building than theory testing.

2) The researcher is separate from the research process in both experimental and ethnographic research.

3) It is usual to analyse both qualitative and quantitative research by statistical analysis.

Answer 3

1 only correct

Question 4

Randomisation is a method of sampling in experiments.

B.
Concepts such as satisfaction and intelligence cannot be operationalised.

C.
All experimental designs are hypothesis testing.

D.
Double blinding in experiments eliminates confounding variables.

E.

Answer 4

E.
A patients experience of a radiotherapy treatment would require a phenomenological approach to research if it were to be explored.

Question 5

A researcher predicts that cigarette smoking is related to lung cancer. The medical records of 1000 cancer sufferers are examined and divided into a smokers group and non-smokers group for analysis.
Select ONE correct response
from the following options to indicate the most appropriate research design:
A.
An unrelated experiment.

B.
A retrospective study

C.
A phenomenological approach.

D.
A prospective study.

E.
A related experiment.

Answer 5

A retrospective study

Question 6

phenomenology is related to theory building in what way

Answer 6

phenomenology is related to theory building, as it looks at peoples experiences and their opinions etc first

Question 7

Which of the following statements regarding sampling is true?

Select one:

A.
Random error is inversely proportional to sample size.

B.
Randomisation is a method used for random sampling.

C.
A large sample must always be taken in experiments to minimise bias.

D.
A small sample size would produce invalid results in a phenomenological study.

E.
Clinical randomised controlled trials always use a random sample of research participants.

Answer 7

Random error is inversely proportional to sample size
