Have your students use their computer and Google Sheets to create a scatter plot. Students are asked to pick two variables that interest them, research to obtain at least 15 data points, type their data into Google Sheets and create a Scatter Plot electronically. The program creates the scatter plot for them, will include the trend line, and tell them the equation of the trendline. The students are then responsible for interpreting the graph that was created based on their data and answer the following questions:
1. What type of association does your graph show between the data? Is that what you expected?
2. Is the association weak or strong? Explain how you know.
3. Is the graph linear or nonlinear? Explain how you know.
4. Does your graph contain any outliers, clusters, or gaps? If your data does include these, explain what you think caused them.
5. What is the slope and y-intercept of your graph? What do they represent?
Students can them submit their projects electronically to be graded. Once everyone submits their scatter plots you can use the class's scatter plots to do a gallery walk and interpret each other's graphs.
