What are the measures of central tendency？

The measures of central tendency are statistical measures that represent the center or typical value of a set of data. The three most common measures of central tendency are:

1. Mean: The mean is the average of a set of numbers. It is calculated by adding up all the numbers in the set and dividing by the total number of values.

2. Median: The median is the middle value in a set of numbers. It is the value that separates the higher half of the data from the lower half.

3. Mode: The mode is the most frequently occurring value in a set of numbers. It is the value that appears most often.
