GCSE Secondary Maths Age 13-17 - Probability & Statistics: Interpreting Graphs - Explained

The video tutorial discusses a graph drawn by Sam to show TV sales by Sam and Max from Monday to Friday. It identifies three main issues with the graph: the absence of a key, missing labels on the Y-axis, and a missing number on the Y-axis. The tutorial emphasizes the importance of having a key and proper labels on both axes for clarity. Each identified mistake is worth one mark, and the tutorial concludes with a reminder of these essential graph components.
