Probability Through Problems
Why Start with Tree Diagrams?
Age 11 to 14
Why the tree diagram is fundamental to studying probability - and why it should be introduced right from the start.
Probability Calculations from Tree Diagrams
Age 11 to 16
Progression from natural frequencies to proportions to the multiplication rule, and hence to probability trees.
Learning Probability Through Mathematical Modelling
Age 11 to 16
Moving from the particular to the general, then revisiting the particular in that light, and so generalising further.
Tree Diagrams, 2-way Tables and Venn Diagrams
Age 11 to 18
Representing frequencies and probabilities diagrammatically, and using the diagrams as interpretive tools.
Independence and Dependence
Age 11 to 18
When are events independent of each other? Sampling with and without replacement.
Conditional Probability Is Important for All Students!
Age 11 to 18
Understanding statistics about testing for cancer or the chance that two babies in a family could die of SIDS is a crucial skill for ALL students.
