# Skater Quality of Teammate and Quality of Competition

Below you will find definitions for all stats available on the Skater QoT/QoC page.

Each QoT/QoC metric is a weighted average of a player’s teammates’ or opponents’ metric where the weights are the percentage of time a teammate spent playing with a player (QoT) or playing against a player (QoC). For example, TOI/GP QoT is the weighted average of all player’s teammates’ TOI/GP (weighted by percentage of time with teammate or opponent).

The full writeup for this methodology can be found here [future link]

Notes:

- RAPM, GAR, and xGAR data is only available at EV, PP, and SH strength states. If 5v5 is selected, the RAPM, GAR, and xGAR metrics displayed are from the EV strength state (same for 5v4 with PP and 4v5 with SH)
- Negative values for RAPM CA/60 and RAPM xGA/60 indicate stronger defensive performance (teammates or oppponents)
- Positive values for Def GAR/60 and Def xGAR/60 indicate stronger defensive performance (teammates or oppponents)
- If Z-Scores are selected to be displayed (from the “Display” dropdown), positive values indicate stronger offensive and defensive performance for all metrics (RAPM CA/60 and RAPM xGA/60 are inverted)

Metric | Definition |
---|---|

RAPM |
Regularized Adjusted Plus-Minus |

GAR |
Goals Above Replacement |

xGAR |
Expected Goals Above Replacement |

Z-Score |
Also called “Standard Score” – a method to transform all metrics so they are on the same scale. These are interpreted as standard deviations above or below the mean. All Z-Scores are centered around the positional mean (F or D) |
