# Interpolating between statistical table values watch

1. There are questions such as: January 2012, S1, Q7, (b) where the markscheme uses statistical values of (from the normal distribution to 4 decimal places) however, the -value are given to 2 d.p in the tables provided by Edexcel.

Now, I can easy get to by using some linear interpolation:

to find the value that corresponds to - but with the number of marks that the markscheme awards for this value, I can't see my way of doing it possibly being the intended way - what is the intended way for S1?

See the formula booklet (Page 21 of the PDF, Page 19 of the booklet).

They have that table for 'nice' values of p so you should have a look there first.

Note that it's a table for P(Z>z), but hopefully you can see why they chose that value for this question - if not, let me know.

Right, okay, that makes a ton more sense! I've got so I get my value in that table! I didn't know that table existed, to be honest, thanks for that!

Strictly speaking, you have that and so where z = (w-.../...) but I get what you mean, and yes, it is pretty well hidden in the booklet.

That was a Latex fail on my part. I meant:

Many thanks! Enjoyed your new blog post by the way, it wouldn't let me rep you though.Nor can I rep you on this.

Thanks, I am doing revision and keeping track of what I'm learning so I will talk about what I've been learning, I've just been terrible so far on that front, so sorry!

Good luck with your applications by the way (interview invite soon?

How's the Algebra course going? Still lost or are you planning a massive revision session soon to go over the notes and learn it all properly?

Hopefully! Interview invites go off starting next week!

Still lost, just building up momentum by doing other modules

Good luck!

There used to be actual threads for A level, it used to be called the A Level Megathread. Are these still going?

I've heard of those before, and I'm pretty sure they're still going and they'd be in the Sixth Form -> A-Level subforum.

Although, there's specifically an A-Level thread for Maths and Further Maths in this forum if that's what you're looking for.
11. most advanced calculators have normal table functions.

Yeah, I've got a TI-Nspire, cba to use it though.

Are there optional modules for Euclid's Elements?

Sorry I was meant to ask if there was an optional module where you use sophisticated ways to derive geometric formulas.
18. Can't rate on iPad, cheers. Can you post A2 level stuff on it?

I think you can see these pages:

I haven't looked too much into the pure options for 3rd year and beyond so I'm not sure, but there may well be.

If there's anything else we can VM as this thread has served it's purpose.
