**HL Maths Paper 2 before/after**

ahmdoda

i think just like paper one no proofs might come up expect those geametery proofs

peekachoo

I hope they give us a construction for 6A

i havnt a clue i found this on

this webpage proofs and other i think and i was like is it up to date cause i havnt a clue honestly

Does anyone know if the Tukey quick test is on our course this year? I've come across it in an Educate sample paper and I can't remember having done it in class?

I don't think so. I don't think I've ever heard of it

Think I read that it's off the course this year, not 100% sure though

check the contents of your papers it will tell you if its off, if its the HL papers it is

It is not on. The contents page in Educate's papers tells you what is not on the course from the older SEC sample papers.

Guys do you know for Scatter plot diagrams? How does one know which axis to plot the data on?

X is the explanatory/independent variable and Y is the response/dependent variable

That doesn't really explain it to me. in lay mans terms? Say for age and finish time or age and height?

I'd say x for both because age is more of a permanent value if you get what I mean?

so x is the permanent one?

Do we need to be able to get the standard deviation manually or just through the calculator? Thanks

Leaving Cert Student

It's in the list with correlation coefficient under its usual symbol!

Aaaand in simper terms...:P The information will more than likely be given to you on a frequency table, the top row goes on the x-axis, bottom on the y-axis.

Guys in Probability, will they ask basic probability like permutations, choosing and factorials? I have no clue on how to do them

I doubt it. If it's a 25 marker it'll probably be a Venn diagram/conditional probability/whether or not something is independent/Bernoulli trials (maybe the bit of theory about theory.)

Am I right in saying that there'll definitely be a choice between a theorem (and those definitions and/or proof by contradiction) and the geometry? Cause our class have done no geometry to standard of in 6B in the exam papers!

Afaik yes. We haven't really either so I'm thinking that way. Although we may not be asked to prove a theorem but rather, apply it. whichever.

Bring it on!

Hope we wont have to draw the line of best fit! So sh1te at that it's not even right!

Do you put in two values for standard deviation? X and Y variables on casio calculator?

Slow Show

For anyone who, like me, was clueless of how to do standard deviation on the calculator until tonight:

Just make sure to draw it through x bar, y bar. Apparently you lose marks if you don't.

do you know that if you are given a table of data, you can use your Casio calculator to get it perfectly(almost suspiciously) right!

Do tell!

Anyone know how to do sec sample 2013 paper 2 Q 5 b ? Pg 156 of exam papers.. Can't figure it out

weirdspider

Is anyone else too scared to look at the P1 thread? I'd be too put off if I got Qs wrong... I'd rather remain ignorant until August!
