📌 Your Profile: Average arrival of 09:02 with a standard deviation of 00:17 (3.2% coefficient of variation). Very predictable ✓

Arrival Time Trend

Arrival Time Trend
📌 This plot shows your arrival time trend over time with a polynomial curve. Are you getting earlier or later as time goes on?

Distribution Analysis

Distribution of Arrivals
📌 Red dashed line = mean, Green dashed line = median. The shape of this histogram reveals your typical arrival pattern.

Weekday Patterns

Weekday Analysis
📌 Error bars show ±1 standard deviation. Which day do you arrive earliest? Which is most variable?

Monthly Trends

Monthly Analysis
📌 Boxplots show the distribution each month. Wider boxes = more variation, longer whiskers = more extreme arrivals.

Calendar Heatmap

Heatmap Calendar
📌 Darker colors = earlier, brighter colors = later. Spot patterns across weeks at a glance.

Streak Detection: On-Time vs. Late Timeline

Streak Timeline
📌 Green = arriving by 9:30 AM (on-time). Red = arriving after 9:30 AM (late).
Longest on-time streak: 79 days | Longest late streak: 2 days

Std. Deviation 00:17 Typical variation from mean
Coeff. of Variation 3.19% Very predictable ✓
IQR (Interquartile Range) 00:21 Spread of middle 50% of data
Range 02:04 Earliest to latest arrival span
Skewness -0.128 Symmetric
Earliest Arrival 08:02 Your earliest recorded arrival
Latest Arrival 10:06 Your latest recorded arrival
On-Time Rate 96.0% Share of arrivals by 9:30 AM

🎲 Statistical Significance: Do Weekdays Matter?

Kruskal-Wallis H-Test (non-parametric ANOVA)

Test Statistic (H) P-Value Result
32.6113 0.0000 ✓ SIGNIFICANT (p < 0.05)
📌 p < 0.05 means weekday significantly affects your arrival time. p ≥ 0.05 means you're equally random across all weekdays.

Poincaré Plot: Today vs. Yesterday

Poincare Plot
📌 Points above the diagonal = you arrive later than the previous day. Points below = earlier. Points on the diagonal = perfectly consistent with yesterday. This reveals "arrival inertia"—whether past behavior predicts future arrivals.
