* Age: Younger children have significantly less homework than older children, especially high schoolers.
* Grade level: The amount of homework increases with each grade level.
* School: Different schools and even different teachers within the same school assign varying amounts of homework.
* Country: Homework policies and expectations differ greatly across countries.
* Individual student: Some students may require more time to complete assignments than others.
While some studies attempt to quantify this, the results are broad ranges and often subject to bias. You'd be more likely to find data on average weekly or daily homework time for specific age groups within a particular region. To get a meaningful answer, you'd need to specify these factors.
