The 3 most common measures of central tendency are the mean, median and mode.
- The mode is the most frequent value.
- The median is the middle number in an ordered data set.
- The mean is the sum of all values divided by the total number of values.
Correct
The three main measures of central tendency are:
- Mean: The arithmetic average of a set of values, calculated by summing all values and dividing by the number of values.
- Median: The middle value of a dataset when arranged in order. If there's an even number of values, it's the average of the two middle values.
- Mode: The value that appears most frequently in a dataset. A dataset can have one mode, multiple modes, or no mode at all.
