Exercise 8: Measures of Central Tendency: Mean,
Median, and Mode
1. The number of nursing students enrolled in a particular nursing program between the years of
2010 and 2016, respectively, were 563, 593, 606, 520, 563, 610, and 577. Determine the mean
(X), median (MD), and mode of the number of the number of the nursing students enrolled in
this program. Show your calculations.
Mean: 563+593+606+520+563+610+577=4032/7=576
Median: 520, 563, 563, 577, 593, 606, 610; median= 577
Mode: 520, 563, 563, 577, 593, 606, 610; mode=563
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 this complication?
Inpatient complication in Table 2: AMI post admission for patients admitted with UA
8%
3. Does the distribution of inpatient complications have a single mode, or is this distribution
bimodal or multimodal? Provide a rationale for your answer.
Single mode because no other complication has the same number.
