Your Head of Clinical Practice Has Followed Your Advice and Now

question 8

Multiple Choice

Your head of clinical practice has followed your advice and now wants you to measure effect sizes. You report a Pearson's r of 0.50 for the impact of increased consumption of oily fish supplements on the symptoms of dementia. Your head of clinical practice wants to know if this is bad, as she remembers that a p-value of 0.30 is not good. What do you tell her?

• A) You tell her that effect size and p-values are the same and that a Pearson's r of 0.50 means there is no statistically significant effect and oily fish supplements should not be given to dementia patients.
• B) You tell her that effect size and p-values are not the same and that a Pearson's r of 0.50 is a large effect, suggesting she should encourage the use of oily fish supplements in dementia patients.
• C) You tell her that effect size and p-values are not the same and that a Pearson's r of 0.50 is a small effect, suggesting she should stop the use of oily fish supplements in dementia treatments until more data analysis is done.
• D) You tell her that effect size and p-values are not the same and that a Pearson's r of 0.50 is a medium effect, suggesting she should encourage the use of oily fish supplements in dementia treatments.
