Mr Brewin’s Y10 Stats GCSE

Mr Brewin — Fri, 11 Feb 2011 10:30:06 +0000

As promised, some links you can explore over the weekend to do with reaction times:

http://www.humanbenchmark.com/tests/reactiontime/index.php
This site gives a simple on screen test with the top 100 results recorded.

http://www.sciencejoywagon.com/explrsci/media/reflex.htm
This site provides a simple test for sight and sound.

http://www.break.com/index/sheepshooting.html
This game gives you times based on recognising movement.

http://reflex.sosocial.net/reactionbutton.php
Start/Stop button test

http://getyourwebsitehere.com/jswb/rttest01.html
Traffic Light test. Top 5 scores are available for comparison.

http://faculty.washington.edu/chudler/java/dottime.html
Hitting dots as they appear.

It would be good if you could explore which sites might be of use. I don’t mind if you make a note of the web address so you can put it into your plan.

Remember, when talking about your hypotheses and how to test them, your plan should have two main themes:

1. What Data Should Be Collected?

You need to think about:

• What is the population from which the data will be collected?

• How reliable is the data?

• What data is to be collected and how will it be recorded?

• Which sampling method will be used and why?

• How large should the sample be?

• What problems might arise and how will they be overcome?

• How might bias arise and how can this be minimised?

• How could the data be collected?

• What data sheets will be required?

If you are collecting data in groups you’ll need to give an explicit account in your plan of how you will do this.

2. What Statistical Techniques Can Be Used?

Think in particular about how you can collect bivariate data so that you can use the more advanced techniques that we have done.

Good luck thinking about it over the weekend!

Mr Brewin’s S1 – The Spirit Level

The slides I was talking about are embedded below. They are from a debate between the authors of The Spirit Level (you can buy it here) and their detractors (who have been shown to be wrong, and wanting to dispute the evidence for ideological reasons). The audio of the debate can be found here.

The powerpoint on correlation and PMCC can be found here.

The ‘Joy of Stat’s programme I was talking about is on iPlayer here (need to watch it soon as it’ll soon expire) and the ‘More or Less’ podcast can be found on their website too. Well worth listening to.
