Determine the Coefficient of Variation for each of the three (3) surveys as indicated below.

1) Patient Satisfaction, Admission Department (see Figure 12.5). Show your work.

2) Patient Satisfaction, Medicine Department (see Figure 12.6). Show your work.

3) Patient Satisfaction, Surgery Department (see Figure 12.7). Show your work.

4) Is it better to have a high mean value of patient satisfaction and high variation, or a moderate mean and low variation? (Hint: Mean survey responses are between 0 -5 and the Standard Deviations are between 1 - 3). Circle your answer.

a) high mean/high variation because it provides greater detail for problem-solving.

b) moderate mean/low variation because low variability offers a greater result consistency.

5) Which of the three (3) departments would you target first and which ratio would you seek to improve first, the mean or the variation? Circle your answer.

a) Admissions, because it has the lowest mean, which creates ambiguous results.

b) Medicine, because its variation needs to increase for greater result accuracy.

c) Surgery, because its variation needs the most improvement of all departments.
