Which ranked data column represents the correct ranking for these data?

A psychologist wants to investigate whether children with Foetal Alcohol Syndrome (FAS) have different working memory performance compared to matched controls (children of the same age and sex without FAS). The task used was a computerised task where the children need to find six different ‘tokens’ hidden in boxes. The outcome measure was the total number of errors (returning to boxes previously checked).

 

In the table below (Output 1), the scores presented in the left hand column represent each participant’s error score. The second column contains the group that each participant was in. The final four columns represent possible rankings for the scores that will be used in non-parametric analysis.

 

Output 1

 

  1. a) Which ranked data column represents the correct ranking for these data? Explain your answer.

 

  1. b) Report the result of the analysis used to test the hypothesis, making an appropriate conclusion. See the Output 2 below and on the following page.

QUESTION 2

 

Previous research has focused on the experiences of mothers in the first year of their child’s life. A researcher is interested in exploring the lived experiences of first time fathers. They have a completely open mind about what they might find and are interested in the individual perspective of participants.

 

  1. State which epistemological approach you would take to answer this research question, and explain why you think this is the most appropriate approach. (Positivist approach or Phenomenological approach or Constructionist approach)

 

  1. State which method you would advise the researcher to use to collect the data, and explain why you think this is the best method. (Quantitative methodology or Qualitative methodology)

 

  1. State which data analysis technique you would advise the researcher to use, and explain why you think this is the best technique.

 

 

 

QUESTION 3

 

Researchers were interested in whether keeping a record of symptoms would improve adherence to taking medication (with adherence measured as a percentage of the total medication prescribed).

The degree to which participants adhered to their medication was measured using an inhaler that records each time the participant takes their medication.

The researchers hypothesised that keeping a record of symptoms would result in participants remembering to take their medication more regularly than before they started keeping a record.

 

  1. Explain what assumptions you would need to check to assess whether a parametric or non-parametric test should be conducted. Explain what graphs you would use to come to your decision.

 

 

 

 

 

 

Output 3

  1. b) Report the result of the analysis (see Output 3 above) and make an appropriate conclusion.

 

 

  1. Give the effect size and discuss what this means in relation to the hypothesis

 

  1. Taking the whole output into consideration (comparing the means, the t-test outcomes and effect size), explain whether the effect of this intervention is meaningful or not in the context of cystic fibrosis treatment.

 

 

 

 

QUESTION 4

A team of researchers want to carry out a study with health care professionals to see whether there is a relationship between their levels of perceived stress, levels of mindfulness and their levels of job satisfaction.

The output from the analysis (Output 4) can be found on the following page.

  1. Report a full analysis of the results with an appropriate conclusion.

 

  1. A government think tank states that all workers need to engage in mindfulness to ensure they have good job satisfaction and low levels of stress. Is this a valid statement to make? Explain your answer in full.
