Working with frequencies

Random sequences are interesting in their own right. However, data that is presented in the form of a list is not particularly easy to analyse. You may have already arranged …

Collecting data 2

How good is simulated data? You should now have two sets of data for our experiment: A set of ‘real’ data, collected using a spinner. A set of simulated data, …

A spreadsheet model

We can also use a spreadsheet to simulate experimental data. Download the provided spreadsheet, ‘Simulation 1’. This has been set up to provide a simulation of the experiment that you …

Collecting data

Now you can use your paperclip and the supplied spinner template to collect some experimental data. We are going to use the spinner as a tool to explore a very …

Making your own spinner

Now make your own spinner. You will need: A printed copy of ‘Spinner Template for Step 1.8’ A paperclip A pen or pencil to act as a pivot Carefully unfold …

Making a spinner

We will be making considerable use of spinners. Watch the video to see what a basic spinner looks like, and how to make one using a paperclip and the supplied …

A better approach?

Having considered some of the problems involved in teaching probability, it is time to present the main features of an alternative (and, we believe, better) approach . Our approach is …

The problem with probability

International studies of mathematics reveal that the teaching of probability takes up relatively little time within the mathematics timetable. This is simultaneously disappointing and unsurprising. Disappointing because probability and the …

Real-world probability

Probability is perhaps one of the topics from school mathematics that are used most often in the real world. We use ideas of probability all the time, often without really …

What exactly is probability, anyway?

It is important – but surprisingly difficult – to be clear about what we mean by probability. In fact, probability can mean very different things to different people! Some popular …
