To plot a time series at GCSE students are taught to choose suitable axes from the data available and recognise trends over time. As learning progresses students begin to consider seasonal changes and hypothesise for their occurrence.
Differentiated Learning Objectives
- All students should be able to recognise and describe a trend over time from a time series.
- Most students should be able to plot a time series and trend line to describe upwards, downwards or level trends.
- Some students should be able to recognise and describe seasonal variations from a time series.
