About Descriptive Statistics

What they tell us:

  • Mean: Average value
  • Median: Middle value (50th percentile)
  • Mode: Most frequent value
  • Std Dev: Measure of spread
  • Skewness: Distribution symmetry
  • Kurtosis: Tail heaviness

Interpreting Skewness:

  • 0: Perfectly symmetric
  • >0: Right-skewed (long right tail)
  • <0: Left-skewed (long left tail)
  • ±0.5: Moderately skewed
  • ±1: Highly skewed
Data Requirements

For Reliable Analysis:

  • • Minimum 3 data points (preferably 10+)
  • • Quantitative (numeric) data
  • • Independent observations
  • • Check for data entry errors
  • • Consider outlier impact

When to Use Each Measure:

  • Symmetric data: Use mean
  • Skewed data: Use median
  • With outliers: Use IQR over std dev
  • Normal distribution: All measures valid
