Statistic Types and Methods
This document provides a comprehensive overview of all statistics, detailing their methods, metrics, units, and descriptions. The table below summarizes the key features supported by each statistic.
Statistics
The following table lists all the statistics available, along with their descriptions, applicable methods, associated metrics, units of measurement, and output precision.| Label | Description | Methods | Metrics | Unit | Output Precision |

| distance_total | Total distance covered across all activities, calculated using the union of intersecting values. | intersect_union_sum | distance distance_walking distance_cycling distance_running | meters | 4 |
| distance_walking | Total distance covered while walking, aggregated using intersecting values. | intersect_sum | distance_walking | meters | 4 |
| distance_cycling | Total distance covered while cycling, aggregated using intersecting values. | intersect_sum | distance_cycling | meters | 4 |
| distance_running | Total distance covered while running, aggregated using intersecting values. | intersect_sum | distance_running | meters | 4 |
| calories_burned_basal | Calories burned at rest (basal metabolic rate), aggregated using intersecting values. | intersect_sum | calories_burned_basal | kcal | 4 |
| calories_burned_active | Calories burned during active periods, aggregated using intersecting values. | intersect_sum | calories_burned_active | kcal | 4 |

| heartrate_max | Maximum recorded heart rate, providing insights into peak values. | max | heartrate | bpm | 0 |
| heartrate_min | Minimum recorded heart rate, providing insights into lowest values. | min | heartrate | bpm | 0 |
| heartrate_resting | Average resting heart rate, calculated using duration-weighted average. | duration_weighted_avg | heartrate_resting | bpm | 0 |
Methods
The table below provides details on the various methods used in the statistics, including a brief description of each.| Label | Description |
|---|---|
| intersect_sum | Sum of intersecting values of specified metrics, aggregating overlapping data points to provide a total count or sum. |
| intersect_union_sum | Sum of the union of intersecting values, merging several metrics to provide a comprehensive aggregation across multiple metrics. |
| sleep_score | A score representing the quality of sleep, calculated using intersecting values. |
| duration_weighted_avg | Average of values weighted by their duration, ensuring longer durations have a greater impact on the average. |
| max | Maximum value of the specified metrics, providing insights into the peak values recorded. |
| min | Minimum value of the specified metrics, providing insights into the lowest values recorded. |
