Recall rate is a way to measure how well someone remembers things they have learned. Imagine if you were playing a game where you had to remember a list of words or numbers. Your recall rate would be how many of those words or numbers you can remember correctly.
For example, if someone told you a list of 10 numbers and you were able to remember all 10 of them, your recall rate would be 100%. But if you could only remember 8 out of the 10 numbers, your recall rate would be 80%.
Recall rate can also be used to measure how well you remember things over time. Let's say that same person gave you the same list of 10 numbers a week later and you were only able to remember 5 of them. Your recall rate for that second test would be 50%.
So, recall rate is just a way to measure how well you can remember things you've learned, whether it's in a game, in school, or in real life. The higher the recall rate, the better you are at remembering things!
