What is a random pattern?
How do you choose your planting levels to minimise the total loss at harvest time?
How is the length of time between the birth of an animal and the birth of its great great ... great grandparent distributed?
Can you create random variables satisfying certain conditions?
When is an experiment described by the binomial distribution? Why do we need both the condition about independence and the one about constant probability?
Are these scenarios described by the binomial distribution?
This article offers an advanced perspective on random variables for the interested reader.
When five dice are rolled together which do you expect to see more often, no sixes or all sixes ?
This tool allows you to create custom-specified random numbers, such as the total on three dice.
Use the computer to model an epidemic. Try out public health policies to control the spread of the epidemic, to minimise the number of sick days and deaths.
Can you work out the means of these distributions using numerical methods?
Can you build a distribution with the maximum theoretical spread?
Use your skill and judgement to match the sets of random data.
This pilot collection of resources is designed to introduce key statistical ideas and help students to deepen their understanding.
Typical survey sample sizes are about 1000 people. Why is this?
This article explores the process of making and testing hypotheses.
