Measurable and Quantifiable

See page 126 of our notes. Also covered in the lectures for that chapter.

Sir, I did go over the notes+PP but still the difference is unclear. At best what I understood is that measurable = predicting without a number or percentage. Whereas, quantifiable = having the ability to predict with good accuracy the figure or percentage.

That is exactly it. Measurable = difficult to predict, but you can measure retrospectively. For example, it is difficult to predict the effect of Brexit on the UK economy, but in 5 years' time we will be able to measure it. Quantifiable, you can predict with good accuracy in advance.
