Worked Solution & Example Answer:As part of your psychology course, you were required to carry out a practical investigation when studying biological psychology - AQA - A-Level Psychology - Question 7 - 2019 - Paper 1
Step 1
State the research hypothesis for your practical investigation in biological psychology.
Answer
The research hypothesis for my practical investigation is that there will be a negative correlation between age and attitude to drug use, indicating that as age increases, lenient attitudes towards drug use will decrease.
Step 2
Describe the results of the statistical test you carried out for your practical investigation in biological psychology.
Answer
The results of the statistical test, using Spearman's rank correlation coefficient, yielded a value of -0.985. This indicates a very strong negative correlation, meaning that as participants’ ages increased, their attitudes towards drug use became progressively more stringent.
Step 3
Explain one strength of the practical investigation you carried out when studying biological psychology.
Answer
One strength of the practical investigation is that the study controlled for age and attitude to drug use by using the same survey questions for all participants. This consistency allows for reliable testing and replication of results.
Step 4
Explain one improvement you could make to the practical investigation you carried out when studying biological psychology.
Answer
An improvement could be to incorporate open-ended questions into the survey, enabling participants to express their attitudes towards drug use in more depth. This would provide richer qualitative data, enhancing the understanding of their beliefs and motivations.
