Let me clarify you this with a similarity:
Envision that, your sweetheart gave you a birthday shock each year throughout the previous 10 years. At some point, your sweetheart asks you: 'Darling, do you recall all the birthday shocks from me?'
To remain on great footing with your sweetheart, you have to review all the 10 occasions from your memory. In this manner, review is the proportion of the quantity of occasions you can accurately review, to the all out number of occasions.
In the event that you can review each of the 10 occasions effectively, at that point, your review proportion is 1.0 (100%) and on the off chance that you can review 7 occasions accurately, your review proportion is 0.7 (70%)
Be that as it may, you may not be right in certain answers.
For instance, we should accept that you removed 15 speculations from which 10 were right and 5 weren't right. This implies you can review all occasions yet not all that decisively
Along these lines, accuracy is the proportion of various occasions you can effectively review, to the all out number of occasions you can review (blend of right and wrong reviews).
From the above model (10 genuine occasions, 15 answers: 10 right, 5 wrong), you get 100% review yet your exactness is just 66.67% (10/15)
