I do say in the lecture that although you could be expected to calculate ‘b’ (the formula is given on the formula sheet) it will almost certainly be given to you in the exam.

‘x’ would obviously always be given, otherwise there would be no question to ask!!

Hello John Sir, thank you so much for explaining learning curve so well. I appeared for F5 exam yesterday and as u said examiner asked that tricky learning curve question total 3 questions in mcq from learning curve worth 6 marks. Only because of you Sir i was able to do it..thanks a lot from my side. Hopefully one day i can donate to a very good study resource like open tuition..tq

Hello John, Do i need to show the avg time calculation on the main part of the calculation as a working or i can calculate that in calculator and just write down that y=90.114

For a question is Section A or B of the exam, nobody will look at your workings and so how you do the calculation does not matter. For a question in Section C, then best to show your workings because the marks are for the workings and not for the final answer.

Hi teacher, thank you for your great help you always gave us, and really we so proud to be part of your community and i’m sure we won’t forget your efforts you gave us all the time.

Dear John,please help how can i differentiate the double rule and the formula rule ? In the example 3 first question, you choose to use the doubling effect rather than the formula? If i choose the formula and just calculate first 15 batches and subtract agin 14 batches, it won’t give me the same answer if i choose the doubling effect? So, how can i know when to choose the doubling or the formula? If i work both of them, will i get the same answer? Please help me .

In this example what you suggest will certainly not give the same answer, because the question does not ask for the time for batch number 15! It asks for the time to produce the next 15 batches, given that they have already produced 1. So it is the total time for 16 less the time for the first.

You can always use the formula, but doubling is easier if the number of units comes as a result of doubling – which means it is limited to 2, 4, 8, 16, 32 and so on.

However you can only be expected to calculate it using the ‘doubling rule’ backwards, and I do show how to do it in my lecture working through the December 2014 Section B question 1.

Hi sir, I have not seen any of your new lectures talking about how the come up with the learning rate if asked. Is this requirement still in the syllabus for march 2017 exams? If yes where can i find a lecture which will show how to calculate the leaning rate?

I thought it was in the lecture but it seems not – I will add a lecture on it. (Although it is simply application of the doubling rule which is of course explained)

Thank you John for the free lectures – they are very clear & a great help! Laughed at the part in video (32:42) about us cursing you for an error – we can’t do that, you are helping us alot. My observation is that the answers on times series and regression analysis were left in the notes I downloaded not sure if you have changed this for the new notes. Thank you once again

hi

i have a question in the exam give the amount of “b” and “x” in the formula “y = ax^b” or not”?

thank

any lecture on calculating the learning rate

John Moffat says

No – I will add one soon.

However you can only be expected to calculate it using the ‘doubling rule’ backwards, and I do show how to do it in my lecture working through the December 2014 Section B question 1.

Sir how did you get 56.25 with your calculator ?

John Moffat says

I multiplied 75 by 75%

elisebowtell says

Hi John,

Is there a lecture on how to find the ‘actual rate of learning curve which occurred? I am confused with the algebra part:

34.3 = 8 x (12.5 x R3)

4.2875 = (12.5 x R3)

0.343 = R3

R = 0.70

i understand all up to 0.343=R3, but don’t see how R=70??

Thank you!

John Moffat says

Yes – it is dealt with in this lecture!

You have written the first equation wrongly.

34.3 = 8 x (12.5 x R^3) (R^3 means 拢 to the power 3, i.e. R cubed)

So 0.343 = R^3

Therefore R = the third root of 0.343 = 0.7
