Which term is a measure of the middle of a statistical distribution?

• A. Career planning
• B. Cause-and-effect diagram
• C. Certification
• D. Central tendency

Answer: (D)

The main idea is identifying a measure that represents the center of a data set. Central tendency describes where data tend to cluster and provides a single value that represents the typical or middle value of a distribution. It includes common measures like the mean (average), median (middle value after ordering), and mode (most frequent value). In HR and analytics, you use central tendency to summarize data such as average salary, typical test scores, or the most common performance level. The other terms refer to unrelated concepts: career planning focuses on an employee’s path and goals, a cause-and-effect diagram is a quality tool for identifying root causes, and certification is a credential you earn. None of these describe a statistical measure of the middle, which is why central tendency is the correct term.
