A research drone was used during a field survey from June 2 through June 10. The table shows every event during that period that changed the drone’s battery level. The battery level is expressed as a percentage of full charge. A positive change indicates that the battery was recharged, while a negative change indicates that battery charge was used. Changes in battery level are measured in percentage points. In each row, the battery level shown is the level immediately after the event. The battery level did not change except during the events shown.
