Understanding Averages

The term "average" usually refers to the Arithmetic Mean, which is calculated by adding up all the numbers in a set and then dividing by the count of those numbers.

Formula: Mean = (Sum of all values) / (Number of values)

Other Measures of Central Tendency

  • Median: The middle number in a sorted list. It is less affected by extremely high or low values (outliers) than the mean.
  • Mode: The number that appears most frequently.
