📈 Understanding the Statistics
When to Use Each Measure:
Mean (Average):
- Best for normally distributed data
- Sensitive to outliers
- Use for: Test scores, temperatures, measurements
Median (Middle Value):
- Best for skewed data or with outliers
- Robust to extreme values
- Use for: Income data, housing prices, reaction times
Mode (Most Frequent):
- Identifies most common values
- Can have multiple modes
- Use for: Survey responses, categorical data, peak detection
Range (Spread):
- Shows total variability
- Greatly affected by outliers
- Use for: Understanding data scope, quality control
Advanced Statistics Explained:
Standard Deviation (σ):
- Measures average distance from mean
- Higher values = more spread
- 68% of data within ±1σ, 95% within ±2σ
Interquartile Range (IQR):
- Range containing middle 50% of data
- Better for skewed distributions than range
- Used in box plots to identify outliers
Skewness:
- Positive: Right-skewed (tail to right)
- Negative: Left-skewed (tail to left)
- Zero: Symmetrical distribution
Kurtosis:
- Measures “tailedness” of distribution
- High kurtosis: More outliers
- Low kurtosis: Fewer outliers
💡 Practical Examples
Example 1: Analyzing Test Scores
Input: 85, 92, 78, 90, 88, 95, 82, 100, 75, 89
Analysis: Normally distributed with mean ~87.4
Use: Mean is appropriate representation
Example 2: Analyzing Income Data
Input: 35000, 42000, 38000, 45000, 120000, 39000, 41000
Analysis: Skewed by high income (outlier)
Use: Median (~41000) better represents typical income
Example 3: Identifying Bimodal Data
Input: 10, 12, 14, 15, 35, 38, 40, 42, 14, 16, 39, 41
Analysis: Two distinct modes around 15 and 40
Use: Indicates two different populations in data
