Statistical Measures
Mean (Average)
Mean = Sum ÷ Count
The arithmetic average of all values. Most common measure of central tendency.
Median
The middle value when numbers are arranged in order. Less affected by outliers than mean.
Mode
The most frequently occurring value(s). Useful for categorical data and finding common values.
Range
Range = Max - Min
Measures the spread or variability of the data set.
Examples
Example 1: Test Scores
Data: 85, 92, 78, 96, 89
Mean: (85+92+78+96+89) ÷ 5 = 88
Median: 89 (middle value when sorted: 78, 85, 89, 92, 96)
Mode: No mode (all values appear once)
Range: 96 - 78 = 18
Example 2: With Outlier
Data: 10, 12, 11, 13, 100
Mean: 29.2 (affected by outlier 100)
Median: 12 (not affected by outlier)
This shows why median is often better for skewed data
