Learning curve

A learning curve is a graphical representation of the changing rate of learning (in the average person) for a given activity or tool. Typically, the increase in retention of information is sharpest after the initial attempts, and then gradually evens out, meaning that less and less new information is retained after each repetition.

The learning curve can also represent at a glance the initial difficulty of learning something and, to an extent, how much there is to learn after initial familiarity.

In economics, learning curve is a curve showing how a firm's costs of producing at a given rate of output fall as the total amount produced increases over time as a result of accumulated learning of how to make the product efficiently using given equipment.
