Understanding Central Tendency
What Are These Measures?
Mean: The arithmetic average, sensitive to outliers (extreme values).
Median: The middle value, resistant to outliers.
Mode: The most common value, useful for categorical or discrete data.
Range: The difference between maximum and minimum values.
When to Use This Calculator
- Analyzing test scores to find average and typical performance
- Identifying the most common value in survey responses
- Understanding data distribution and spread
- Comparing different measures of central tendency
Which Measure to Use?
Use Mean when: Data is symmetrically distributed without outliers.
Use Median when: Data has outliers or is skewed (income, house prices).
Use Mode when: Looking for the most common category or value.
Common Mistakes
- Using mean for skewed data (better to use median)
- Reporting only one measure without considering data distribution
- Confusing mode with median or mean
