Difference between Mean, Median, and Mode

Mean (Average)

The sum of all values divided by the count of values. Best for symmetric distributions.

Mean = (Σx) / n

Example: (5 + 10 + 15) / 3 = 10

Median (Middle)

The middle value when data is sorted. Best for skewed distributions or outliers.

Middle value of sorted data

Example: 5, 10, 15 → Median = 10

Mode (Most Frequent)

The value that appears most often. Can have no mode, one mode, or multiple modes.

Most frequent value(s)

Example: 5, 10, 10, 15 → Mode = 10

When to Use Each Measure?

📊 Use Mean for:

  • • Test scores and grades
  • • Financial data (salaries, prices)
  • • Scientific measurements
  • • Data without extreme outliers

📈 Use Median for:

  • • Income distribution (resists outliers)
  • • Real estate prices
  • • Housing costs
  • • Skewed or asymmetric data

🎯 Use Mode for:

  • • Categorical data analysis
  • • Finding most popular items
  • • Survey responses
  • • Manufacturing (most common defect)

⚠️ Watch Out for:

  • • Mean is sensitive to outliers
  • • Median ignores the magnitude of values
  • • Mode may not exist or be multiple
  • • Always check your data distribution
