### Dice duels: load one dice

Make biased dice. Weight (load) a dice to favour one of the six numbers. For example, load the number six so that it is three times more likely to come up than any other face (probability 4/9). Test ideas about bias by rolling a loaded dice. Look at demonstrations of the mathematical principles of bias. Compare the shape ...

### Dice duels: load a pair of dice

Make biased dice. Weight (load) dice to favour one of the six numbers. For example, load the number five on both dice so that it is three times more likely to come up than any other face. Test ideas about bias by rolling the loaded dice. Examine the sum of the two numbers rolled. Look at demonstrations of the mathematical ...

### Dice duels: find the bias

A dice has been weighted (loaded) to favour one of the six numbers. Roll the dice to work out which is the favoured face. Explore how many rolls are needed for you to be reasonably sure of a conclusion. Look at demonstrations of the mathematical principles of bias. Compare the shape of theoretical data distributions with ...

### Dice duels: load one dice [ESL]

Make biased dice. Weight (load) a dice to favour one of the six numbers. For example, load the number six so that it is twice as likely to come up than any other face (probability 2/7). Test ideas about bias by rolling a loaded dice. Look at demonstrations of the mathematical principles of bias. Compare the shape of theoretical ...

### Dice duels: fair or unfair?

Test dice to see if they have been weighted (loaded) to favour one of the six numbers. Explore how many rolls are needed for you to be reasonably sure of a conclusion. Compare the shape of theoretical data distributions with experimental results. This learning object is one in a series of 11 objects.

### Dice duels

A dice has been weighted (loaded) to favour one of the six numbers. Roll the dice to work out which is the favoured face. Explore how many rolls are needed for you to be reasonably sure of a conclusion. Make biased dice. Test ideas about bias by rolling a loaded dice on its own or with a fair dice. For the dice pair, look ...

### Sampling from a population

This is a website designed for both teachers and students that refers to sampling from a population and taking a census from the Australian Curriculum for year 8 students. It contains material on cross-sections of sampling and how the means and proportions of samples vary. There are pages for both teachers and students. ...

### Impact of coming to school on carbon emissions

How big is your carbon footprint as you travel to and from school? Watch Daniel O'Doherty, 2008 'Action Against Climate Change' Eureka Schools Prize winner, as he determines his hypothesis then designs and conducts a study about carbon emissions. Listen to the recommendations he makes to reduce and offset the emissions ...

### Same birthday: what's the chance?

Mathematician Adam Spencer answers a question about something called the 'birthday paradox'. Find out what this has to do with birthdays and the number of people in a room.

### Spinners: assessment

Test your understanding of chance by constructing coloured spinners (dials with pointers) according to given criteria. Choose up to twelve equal-sized parts. Choose up to three colours for the parts of each spinner. There are 16 different tasks. For example, make a red and blue spinner with seven parts so that the chance ...

### Dice duels: two dice: assessment

Test your understanding of what occurs when dice are biased and your ability to distinguish between biased and uneven distributions. Interpret graphical representations of the results of rolls of dice to determine whether or not dice have been biased. Predict results when dice have been biased and faces are combined. Bias ...

### Dice duels: one dice: assessment

Test your understanding of what occurs when a dice is biased. Interpret graphical representations of the results of rolls of a dice to determine whether or not the dice has been biased. Use your understanding of even distributions, sample size and random variation to identify which face has been biased. This assessment ...
