Hi sir,
I am quite confused which method to use when dealing with learning rate effect.
May I know when i should use formula, i.e. Y = ax^b ;
When to apply step-by-step calculation (as follow) ?Step-by-step calculation: (LR at 75%)
Unit…………Time/unit……….Total time
1…………….12…………………12
2……………..9………………….18
4……………..6.75……………..27
8……………..5.0625………….40.5For your reference, this question is from “Specimen Exam applicable from September 2016 Question 21 and 22.
Please kindly advise.
Thank you.
What you (for some reason) call the step-by-step calculation is applying the doubling rule, which is relevant when production doubles each time.
If it does not involve doubling then you need to use the formula.You need to watch my free lectures on this to understand – I explain and work through the examples in our free lecture notes (and I am not going to type out all my lecture here 🙂 )
The lectures are a complete free course for Paper F5 and cover everything needed to be able to pass the exam well. (You cannot learn what is necessary just from practicing the specimen exam – you need to study the topics first)
