The three measures of central tendency are:
AMean, range and mode
BMedian, range and total
CMean, median and mode
DMode, range and frequency
Answer & Solution
Correct answer: C. Mean, median and mode
1. A measure of central tendency is a single number standing in for a whole data set.
2. The three studied are mean, median and mode.
3. The mean is the arithmetic average, the median the middle value, the mode the most frequent value.
4. Range is a measure of spread, not of centre, so any option containing it is wrong.
