Statistics - Introducing Line Graphs - Worksheet

The worksheet 'Introducing Line Graphs' is designed to help children understand how to read and interpret line graphs, with a particular focus on continuous data such as time and temperature. It begins by teaching them to use scales to accurately read a time graph, emphasizing the importance of understanding that continuous data can be measured. Students are presented with line graphs depicting temperatures at different times of the day across various months, and they are tasked with answering questions that require them to retrieve simple information directly from the graphs, as well as explain how to find data points that are not explicitly marked.

Further exercises on the worksheet challenge students to use their reasoning and problem-solving skills to identify mistakes in reasoning based on the given graphs. For example, they are asked to critique a statement about the number of dogs in a park at a certain time, which is incorrectly represented as a fraction on a line graph. The correct approach is discussed, highlighting that discrete data such as the number of dogs should be presented using a bar chart, pictogram, or table instead of a line graph. Additionally, the worksheet includes questions that require students to deduce temperatures at specific times by drawing horizontal and vertical lines on the graphs, reinforcing their understanding of how to interpret data between given points.
