Calculating the Mean, Median, and Mode

In statistics, the mean, median, and mode are measures of central tendency used to describe a set of numbers.

• Mean: To find the mean, add up all the numbers in the set and then divide by the total count of numbers. \begin{equation} \bar{x} = \frac{\sum_{i=1}^{n} x_i}{n} \end{equation}

• Median: The median is the middle number when the numbers are arranged in ascending order. If there is an even count, the median is the average of the two middle numbers.

• Mode: The mode is the number that appears most frequently in the set.

Understanding these measures helps in analyzing data effectively.
