Understanding Graphs: Choosing the Right Type for Data Representation

This lesson focuses on the fundamentals of graphs, their uses, and how to select the most appropriate type for specific data. Students will collaboratively create graphs and independently complete associated worksheets to assess their understanding. Key concepts include procedural knowledge for investigating data to draw conclusions, and declarative knowledge to recognize graph relationships and selection criteria. The lesson also encourages reflection on graph interpretation techniques and provides resources for further exploration.

  2. Feed Forward Prior Knowledge of graphs . Looking over the basics of graphs, how and when they are used. http://tfssbio.pbworks.com/f/Choosing+Appropriate+Graphs.pdf. Creating a graph together as a class http://gostats.com/resources/types-of-graphs.html Lesson . Working through the learning object together as a group . Students will work on their own to complete the question provided . Short evaluation of other resources .Reflection and question time

  3. Procedural and declarative knowledge Procedural Knowledge- Investigating data in different ways to make comparisons and draw conclusions.- Identify the relationship between graphs-Identify the most appropriate graph for-Construct a graph using the Learning object-Compare techniques for collecting data-Make comparisons and draw conclusions as to why some graphs are more suitable to a topic then others.- Compare shapes of box plots to corresponding histograms and dot plots. Declarative Knowledge- Understand the relationship between graphs-Understand and select the most appropriate graph for the given data-Recognise the most appropriate technique for interpreting information into graphsunderstanding the different types of graphs ad how they are interpreted
