Why Averages Matter

Averages help simplify large sets of information into a single value that is easier to understand and compare. Whether you're reviewing grades, monitoring investments, analyzing business performance, or tracking sports statistics, averages provide valuable insight into overall trends.

Average vs Median vs Mode

• Statistic: Mean (Average)
  Description: Sum of all values divided by count

• Statistic: Median
  Description: Middle value when numbers are sorted

• Statistic: Mode
  Description: Most frequently occurring value

While the average is the most commonly used measure, median and mode can sometimes provide better insights when data contains extreme values or outliers.
