Using a regression applet, your class can predict and explore the shape of the residuals of linear and non-linear data. Then through discussion, these learners can generate rules on how to analyze residual plots to recognize non-linear data. Round out the lesson with an investigation regarding SAT scores and best fit regression models. For an extra challenge, have the class use the regression applet to try to generate scatter plots to match given residual plots. Note: the Data Sets for Algebra I Handout mentioned as an optional resource is not available.
In this Algebra I/Geometry/Algebra II worksheet, students create a scatter plot and analyze the data to determine if the data show any type of correlation. The four page worksheet provides extensive explanation of topic, step-by-step directions, and one problem. Answers are not provided.
What better way to generate student excitement than to bring Facebook into the classroom? Here, your class will analyze data on Facebook usage using scatter plots and residuals, and determine which function (linear or exponential) is the more appropriate model. A PowerPoint presentation helps guide your class through several activities, including an exponential growth activity and additional practice.
Adjust this instructional activity to fit either beginning or more advanced learners. Build a scatter plot, determine appropriate model (linear, quadratic, exponential), and then extend to evaluate the model with residuals. This problem uses real-world data and challenges one to make predications based on the model.
Middle schoolers investigate the validity of da Vinci's proportion theory by recording human measurements on scatter plots. In groups of three, they record each other's height and wingspan to create a Powerpoint presentation, chart, or plot demonstrating their conclusions. Using their scatter plot information, they develop a clothing business whose sizes are determined by the plot results.
Students investigate area and perimeter of various shapes. In this area and perimeter of various shapes lesson, students record how area of shapes change when a dimension is doubled, halved, quartered, etc. Students make scatter plots of radii v. circumference and radii v. area. Students discuss why the graphs have a linear or quadratic shape. Students make similar graphs for various shapes such as squares and triangles.
Students create a scatter plot for bivariate data and find the trend line to describe the correlation for the sports teams. In this scatter plot activity, students analyze data, make predictions,and use observations about sports data using a scatter plot to find the line of best fit. Students explore a website and worksheets to complete the project. Students also write an essay and complete a quiz for assessment.
Here are a set of graphing lessons that have a real-world business focus. Math skills include creating a scatter plot or line graph, fitting a line to a scatter plot, and making predictions. These lessons are aimed at an algebra 1 level but can be adapted either for middle school or higher levels.
Students explore the concept of circles. In this circles activity, students use their Ti-Nspire to collect data on various circles of different sizes. Students measure the diameter and circumference of the circles and plot the data in a scatter plot of diameter v. circumference. Students find the slope of the line to be Pi.
This handout begins by asking your statisticians to form hypotheses on the correlation between test scores and student height and test scores and the number of hours watching TV. Then using specific data, your class will create scatter plots, find the line of best fit, calculate correlation values, and discuss the possibility of causation based on their findings.
