Statistics - Line Graphs - Starter

In the realm of statistics, line graphs serve as a powerful tool to visualise data trends over time or across categories. When introducing the concept, a starter activity might involve presenting students with a simple line graph, perhaps illustrating a clear trend or change, such as monthly temperatures or daily footfall in a store. This initial engagement is designed to familiarise students with the key components of a line graph, which include the x-axis (horizontal) and y-axis (vertical), data points, and the connecting line that represents the progression of values.

The starter activity aims to prompt students to observe and interpret the information presented by the line graph. By asking questions about what the graph shows, educators can encourage students to identify the axes labels, understand the scale, and recognise patterns or significant points such as peaks, troughs, or steady states. This sets the foundation for more complex discussions about how line graphs can be used to make predictions, compare different data sets, and draw conclusions from the visualised data. Understanding line graphs is a crucial skill in statistics, as it enables students to effectively communicate and analyse quantitative information.
