Football Recovery Analytics Dashboard

• Shapiro-Wilk p-value > 0.05: Data can be considered normally distributed
• Shapiro-Wilk p-value <= 0.05: Data significantly deviates from normal distribution
• Warning: Results for small sample sizes (n < 8) should be interpreted with caution

Note: The "All Periods" analysis combines data across all periods to provide a more comprehensive assessment with larger sample sizes.

QQ plots compare the observed data distribution to the theoretical normal distribution:

• Points following the red reference line closely suggest a normal distribution
• Systematic deviations from the line suggest non-normality
• S-shaped patterns indicate skewness in the data

Kernel Density Estimation (KDE) plots show the estimated probability density of recovery times:

• Bell-shaped curves suggest normal distributions
• Multi-modal curves (multiple peaks) suggest mixed distributions
• Skewed curves (asymmetric) indicate non-normal distributions
• Dotted line shows theoretical normal distribution for comparison
• Green vertical line shows mean, blue vertical line shows median

These plots show match recovery time trends alongside match events:

• Interactive timeline with team recovery times
• Match events (goals, cards, substitutions) overlaid on recovery data
• Team formation details and tactical shifts
