In year 10 you did "sample to population inference" this standard is just at a higher level.
Think back to "Are Boys Taller than Girls in Year 10?"
You are expected to:
- Research into a familiar context and link what you see throughout the PPDAC cycle to this research
- Integrate informed contextual knowledge throughout the PPDAC cycle.
- Use re-sampling methods (bootstrap confidence intervals) as a tool to answer your investigative question
- Note: we are looking at the difference in means or medians
- Write a research report with meaning and interpretation of the resulting statistical findings.
- You will have one period in the computer lab, and one in class. You will have time to research prior to the Internal.

Making the call up until now http://2013maths.wikispaces.com/file/view/InferenceMakingTheCall.pdf
Now we move to formal inference.
====================================================================================================
Lets Look at what you have done before - and compare it with what you have to do now

So the difference is we are looking at means, not just medians, and we have a new (very cool) tool - > Resampling (Bootstrap)
Resampling (Bootstrap)
A technique in which samples are taken repeatedly from an existing sample or existing samples.
Here are the visuals to use whilst teaching the concept http://www.stat.auckland.ac.nz/~wild/BootAnim/
