What is weighted accuracy (weighted averages)?

Weighted accuracy is when each result is weighted differently in order to calculate a better and fair estimate.

For example in a clinical setting, advice from a clinician with +10 yrs of experience may be given more weight than a trainee clinician.

For the Matrix app, your most recent results are weighted heavier than the older results.
