Definitions to learn:

Spoiler:

(Original post by raheem94)
Here is a list of definitions:

(Original post by Groat)
Adding to raheem's definitions, I've taken the definitions from past papers and bolded the words that you must have to get the marks.

Critical Region: The range of values of the test statistic that would lead you to reject the null hypothesis.
Significance Level: The probability of incorrectly rejecting the null hypothesis.
Sampling Frame: A list of all the members of a population.
Population: Collection of all items.
Statistic: A random variable that is a function of the sample values which contains no unknown parameters.
Sampling Distribution: All possible samples of the statistic and their associated probabilities.
Census: Where every member of the population is investigated.
Sampling Unit: An individual member of the sampling frame.
Sample: A subset of a population.
Hypothesis Test: A mathematical procedure to examine a value of a population parameter proposed by the null hypothesis compared with an alternative hypothesis.

Assumptions for Binomial:
Occurrences are independent.
The probability of each outcome remains constant.
Two distinguishable outcomes.
Fixed number of trials.

Assumptions for Poisson:
Events occur singly.
The rate remains constant.
Events are independent.

Binomial approximated to Poisson:
n is large.
p is small.
Mean is near to the variance.

Binomial approximated to Normal:
n is large.
p is close to 0.5.

Poisson approximated to Normal:
Lambda is large.

A sample instead of a census
Saves time.
Cheaper.
Easier.

A census instead of a sample
Known population.
Easily accessible.
Total accuracy.

Continuity correction
Normal is continuous, whereas poisson and binomial are discrete.

Just completed S2 a few days ago. It looked simple, hypothesis testing took some time to understand, but the other chapters were very easy.

I haven't tried any past papers, but i solved the whole book, including the review exercises, hoping it will be enough.

Optimistic to score full or close to full marks.

What about you?

I mainly need to remember all the definitions really, I'm more worried about FP2/3 tbh... so trying to aim for high marks in S2

I have completed FP2, but only have done 3 chapter of FP3, so i am worried about FP3 rather than other units.

yeah, i've gone through the exercises in the books but still need to do all the past papers, im finding fp2 harder then fp3 at the moment!

S2 is easy. Does anyone have a list of definitions you need to learn? Arsey had a nice one for S1. If not i'll make one.

Hi, have you got any notes for S1?

I'd appreciate it if you can lend me them

I have attached Arsey's notes with this post.

S2 isn't too bad it just requires a bit more thought than S1, hypothesis testing is a bit annoying. But I have C2 at the same time though (Luckily I am already getting 90+ on C2 past papers so I can focus on S2).

[Warfare]

As you can see from my posts in the help forum, its not too good. S2 is easy alot in some parts but then again in some chapters it ticks me off!

Hoping to do well in this module, just need to learn the definitions really. Thanks raheem94

No problem, you are welcome.

hows everyones revision going for this module..i thought people could share their revision tips here and help others out. and just discuss this module

has anyone got all the definitions we need to learn for this module?
it would be really appreciated

[Refrigerator]

ahhh S2...

I haven't started revising for S2 yet but I think I'm already in a good position given how many past papers and practice we've done in class

[godknows]

I need to teach it all to myself and practice it too by 24/05/2012
any good sites there to explain it well ?

This is a good link to learn it.

All the chapter except the last chapter, are well explained in the edexcel book.

Haven't started revising for S2 yet, got almost a whole month between my 2nd last exam and S2! I'll spend it grinding those past papers and making sure I get 100% :P
