Thank you all!
These questions always seem to annoy me, although i've done enough of them!

I think for (b) you just have to state the obvious, ie. that the average male height is around 177cm and that height is broadly normally distributed, so therefore this would be an appropriate way of modelling an adult male's height.

And for (c) perhaps mention that modelling helps us to obtain information (such as probabilities) about a set of data, which we couldn't be too sure about, when referring to just the data itself.

Hope that helps!

I know, i hate stats, half of it isn't even maths. Just memorising equations and implementing them . Thanks anyway

Mathematical models can help to improve our understanding of real-world problems as we are able to vary factors affecting the real-world problem without the consequences. Is that enough for two marks?

Erm, I'm not sure if that'd get you 2 marks, perhaps only 1, as it only seems to be one definite point but then i'm not sure what you could write for the other... hmm, sorry for the uncertainty.

I don't think you'd get any marks for that. The question is asking why this SPECIFIC model (Normal distribution) is a good one, not just why statistical models in general are good

EDIT: Actually this is a good answer to part C (not B, as you stated). I seem to remember though that you should say that a statistical model is better because it does not involve the TIME and COST that a real model would

The two marks would probably be:

Allows you to experiment by changing variables: B1
Without time/cost of real model: B1

Nope, you're wrong. It doesn't say why 'THIS SPECIFIC' model.....

It says 'why mathematical models....' note it has a 'S' at the end of 'models' insinuating the generalisation of Mathematical Model'S'.

Yea, sorry, i was refering to part C. You're correct
