A study was designed to examine student attitudes towards research utilisation in nursing practice (Marshall et al 2007). The Nursing Students' Attitudes and Awareness of Research and Development within Nursing Scale was used to collect data from students enrolled at several Australian schools of nursing
1. Examine the 95% confidence intervals for the mean scores for each university. Based on these, are there any statistically significant differences in mean scores between the universities? 2. The effect sizes (Cohen's d) between the university means were as follows: A and B = 0.02; A and C = 0.17; B and C = 0.14. Using Cohen's conventions, are these small, medium or large effect sizes? 3. Based on your knowledge of statistical power, how confident are you in the interpretation of the following results? What is required to improve the power of this study? (F(df=232) = 0.601; p = 0.549). Post hoc analysis found no difference between all pair combinations of universities p > 0.05.
