Statistics
Title: Relative Frequency and Expected Frequency
Learning Objectives
Grade D
To be able to investigate how likely something is to happen based on either an experiment or history.
How can we find out the chance of something happening in the real world?
Grade C
To be able to demonstrate and find the relative frequency from experimental evidence.
How can we calculate an estimate of the probability of a pin landing point up?
Resources
Grade D
Introduce students to the idea of throwing a pin - has this got equally likely outcomes? (pins needed).
Use the "Relative Frequency Chart" worksheet to record throws (print).
Grade C
Use a tally chart to work out whether in the long term it is more or less likely that we will get a White Christmas in some parts of the UK:
Now ask students to investigate the chance of it raining in December. Set each table a different UK location.
