About Mean, Median, and Mode

This calculator computes three measures of central tendency for a dataset:

• Mean: The average, calculated as \( \frac{\sum x_i}{n} \), where \( x_i \) are the numbers and \( n \) is the count.
• Median: The middle value when numbers are sorted, or the average of the two middle values if \( n \) is even.
• Mode: The most frequent value(s) in the dataset.

For example, for \( \{1, 2, 2, 3, 4\} \): Mean = 2.4, Median = 2, Mode = 2.
