The relationship between patient satisfaction and hours per patient day on a medical unit was found to be (r = 0.60, p < 0.05). What is the correlation between these two values?

1. 0.05

2. 0.36

3. 0.55

4. 0.60

The correct answer is: 0.05

The correlation coefficient, denoted by 'r', is a measure of the strength and direction of a relationship between two variables. In this case, the correlation coefficient between patient satisfaction and hours per patient day is 0.60. This value indicates a moderately strong positive correlation between these two variables. A correlation of 0.60 suggests that as hours per patient day on a medical unit increase, patient satisfaction tends to increase as well. Option A (0.05) is not the correct answer because a correlation of 0.05 would indicate a very weak or close to no relationship between the two variables. Option B (0.36) and Option C (0.55) are also incorrect as they are not the correlation coefficient provided in the question. Therefore, the correct answer is Option D (0.60) as this matches the correlation coefficient given in the question (r = 0.60).
