Which group of measures conveys information about the average value of a set?

• A. Descriptive measures
• B. Descriptive statistics
• C. Measures of central tendency
• D. Probability measures

Answer: (C)

Central tendency describes where data tend to cluster, giving a sense of the typical or average value in a data set. The group of measures that conveys information about that central value includes the mean, median, and mode. These are the statistics you look at to understand the center of the distribution, with the mean being the common arithmetic average, the median the middle value, and the mode the most frequent value. Other options are broader categories or pertain to different ideas: descriptive measures is a broad set of summaries, descriptive statistics is the overall collection of summaries, and probability measures deal with likelihoods, not averages. Therefore, the best choice is measures of central tendency.
