Topic 1 Question 114
You work for a gaming company that manages a popular online multiplayer game where teams with 6 players play against each other in 5-minute battles. There are many new players every day. You need to build a model that automatically assigns available players to teams in real time. User research indicates that the game is more enjoyable when battles have players with similar skill levels. Which business metrics should you track to measure your model’s performance?
Average time players wait before being assigned to a team
Precision and recall of assigning players to teams based on their predicted versus actual ability
User engagement as measured by the number of battles played daily per user
Rate of return as measured by additional revenue generated minus the cost of developing a new model

The game is more enjoyable - the better and "business metrics" points me to user engagement as best metric

A. Average time players wait before being assigned to a team B. Precision and recall of assigning players to teams based on their predicted versus actual ability
These two metrics are the most relevant for measuring the performance of the model in assigning players to teams based on skill level. The average wait time can indicate whether the model is making efficient and quick team assignments, while precision and recall can measure the accuracy of the model's predictions. It's important to balance precision and recall since assigning players to a team with a large difference in skill level could have a negative impact on the players' gaming experience.
C and D are also important metrics to track, but they may not be as directly tied to the performance of the team assignment model. User engagement can indicate the success of the overall gaming experience, but it can be influenced by other factors beyond team assignments. The rate of return is also an important metric, but it may not be a direct measure of the success of the team assignment model.

It's C. The question specifically asks for a business metric. Precision and recall are not business metrics, but user engagement is
