Sir, how do you find the Learning rate if you have the time given for the 1st unit and the time for the 16th unit.
Thank you.
You use the doubling rule.
Making 16 units involves doubling 4 times, so you take the fourth root of ((average time per units for 16 units) / (time for the first unit).
Have you watched my free lectures on this?
Yes sir I have, and I understood how you found the learning rate when you had the average time for 1 and the average time for 4 in the free lectures.
I still find it difficult as to how you find the learning rate when you 16 units at play.
I do apologize for being vague but I once came across such a question and now I cannot find nor recollect what the question was.The only thing I do remember is that they had given the time for 1 unit, the total time for 16 units was given and I was asked to find the learning rate, for which I got the wrong answer.
Thank you for your help sir, but if it isn’t too much to ask, could you perhaps give me a small made up question with figures as the above requirements so i could get a better understanding. I wouldn’t be bothering you with this if I had the question, but I do not wish to leave anything out while preparing for the exam.
Sorry, but I am not going to make up examples here.
A combination of my lectures and questions from your Revision Kit should be more than sufficient (I assume you do have a Revision Kit – you dare not risk attempting the real exam without having practiced every question in your Revision Kit 🙂 )
1 doubles up to 2. Double again and you get 4. Double again and you get 8. Double again and you get 16.
Therefore making 16 involves doubling 4 times.
Therefore the average time per unit when we make 16 units is equal to the average time for the first unit multiplied by r to the power 4 (where r is the learning rate).
It is then a question of simple calculator work.
