A statistic in basketball used to gauge shooting efficiency that takes into consideration points scored from three pointers, field goals and free-throws to get a measure of points scored each shooting attempt.
It is calculated as follows:
Points / (2 * (FG Attempts + 0.44 * FT Attempts))
This is an advanced statistic that expands on field-goal percentage (FG%) to adjust for the fact that not every shot within the FG% is equal.
