A healthcare organisation is looking to understand whether recent high-pressure situations have affected staff moral across several similar healthcare units. They have recently conducted a staff survey from which they have calculated values for the staff stress and moral levels at each unit. They also have data on the proportion of beds in each unit that were full on average and the average percentage of those patients who had the highest possible care needs in the week before the survey. What analysis methods from the course would you recommend that they use to analyse the data? How should they be implemented? What should they look for/expect to get from the results? What should they be careful to avoid when interpreting the results
