respectively, were 563, 593, 606, 520, 563, 610, and 577. Determine the mean(x), median (MD), and mode of the number of the nursing students enrolled in this program. Show calculations.
2- What is the mode for the variable inpatient complications in Table 2 of the Winkler et al. (2014) study? What percentage of the study participants had complication?
3- Does the distribution of inpatient complications have a single mode, or is this distribution bimodal or multimodal? Provide rationale.
4- As reported in Table 1, what are the three most common cardiovascular medical history even in the study, and why is it clinically important to know the frequency of these event?
SOB: Frequency 189 (68%)
Chest Pain: Frequency 255 (92%)

7- Which subscale of Caring Practices had the highest mean? What do these results indicate?
8- Compare the Overall rating for Organizational Climate with the Overall rating of Caring Practices. What do these results indicate?
