Ready, steady, go

Do Year 10 students have faster reaction times than Year 5 students?  The focus of this lesson is on comparing two samples and making an inference about populations from samples.
Students analyse samples in groups. Each group has different samples. Groups report back with OHT of own graphs and conclusions. Teacher uses CensusAtSchool online to demonstrate effect of larger samples on inferences and to show population distribution.
