AQA A level Chemistry Required Practical 7A - Initial rate of reaction

This video examines how to measure rate using an "initial rate" method: i.e. what you would do for a reaction where you time the whole thing, like the iodine clock or the disappearing cross. See 7B for the continuous monitoring method.

Hello, the mark scheme for some of these questions mention graphical calculation for working out the order, would that not be necessary if we do it this way in order to achieve the full 6 marks?

How do you know if they are asking you about the initial rate method as opposed to the continuous method?
