Revision Class

I plan to be at school in LA5 (normal maths classroom) from 1-3pm on Wednesday this week for those who would like to attend. I will have a couple of past exams for you to work through and will recap quadratics/functions and common question types.

Moving Averages

Moving average notes.
Make sure you know the centred moving average formula and origins of it!

Sequence Comments

For the test tomorrow make sure you can fill in gaps in a sequence
For example 2, ___, ___ 16, ... is a geometric sequence find the missing terms, then write the recursive rule.

(Note missing numbers are 4, 8 and recursive rule is T(n+1) = 2T(n); T(1) = 2)

The questions also include finance type contexts so make sure you know percentage increase type questions and be able to use general rules to describe them.

Good luck and see you all in the morning.

Normal distribution

Make sure you understand the concept of normal distribution and the 68%, 95%, 99.7% rule when balanced.
a good practice is to watch the video from http://www.classpad.com.au/

here are the class notes

Sampling Techniques

Here are the notes on sampling. You need to be able to describe how you you would choose a sample.

Good Luck in your exams

Good luck and Study hard for your exams. You are all capable of surprising yourselves in a good way IF you put the work in. Study the topics you know first and then work on the topics you don''t later. Please feel free to ask questions through the blog or e-mail me at the education one. I am planning to check the e-mails and blog each evening to respond to any queries.

Histograms

There is lots of information and activity sites to create histograms. You need to be able to read them and describe distributions and estimate central tendency for this course.

Here a silly and education activities to have a go at.

very silly activity

try to find a video that also shows interpreting histograms. So far I have only found how to draw them!
