Scatter plots tell a story about the data — you just need to be able to read it! Building from the previous lesson in the series where learners created scatter plots, they now learn how to find associations in those scatter plots....

Explore linear functions! In this Algebra I instructional activity, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

Secondary learners investigate exponential functions in a real-world scenario. They collect data on the temperature of a cooling baked potato, enter the data into lists, and graph the data using a scatter plot before finding an...

Using the TI-Nspire calculator, statisicians identify outliers and their effect on the least-squares regression line. In finding the line of best fit, they determine what points will affect the least squares regressions and what points...

Predict the future of education through a mathematical analysis. Using a project-based learning strategy, classes examine the pattern of student-to-teacher ratios over a period of years. Provided with the relevant data, learners create a...

High schoolers organize data from the USA TODAY Snapshot, "Is leisure time really shrinking?" into two scatter plots and determine the quadratic model for each scatter plot. They determine if these graphs intersect and learn the concept...

High schoolers collect height versus time data of a bouncing ball using the CBR 2™ data collection device. Using a quadratic equation they graph scatter plots, graph and interpret a quadratic function, apply the vertex form of a...

Just how far off is the least squares line? Using a graphing calculator, individuals or pairs create residual plots in order to determine how well a best fit line models data. Three examples walk through the calculator procedure of...

Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...

In this Scatter Diagrams and Curve Fitting worksheet, young scholars are guided in how to graph a scatter diagram (plot) and a Best Fit Line using a TI-83 graphing calculator. 

We landed on the moon with less computing capabilities than you can find in this app! Here is a multiple function calculator that takes all the power you get from a handheld and adds the wonderful large screen that only a tablet can...

Young geometers explore relationships between units of measure and objects. Three activities provide varied opportunities to practice. Learners calculate the volume of two cylinders made by rolling a piece of paper vertically and...

Is 0.56 stronger than -0.78? Interpret the correlation coefficient as the strength and direction of a linear relationship between two variables. An algebra lesson introduces the correlation coefficient by estimating and then...

Students explore the concept of systems of equations. In this system of equations instructional activity, students enter data into lists on their calculators about 100 meter dash times. Students plot the points using a scatter plot and...

Students investigate data collection and analysis.  In this Algebra I lesson, students create a scatter plot and find the equation of best fit in a simulation of a leaking water pipe.

Learners explore the concept of distance v. time. They use a CBR to collect data on their distance over time, then plot their data using a scatter plot and find an equation to model their data. Pupils discuss what if scenarios which...

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

Learners explore scatter plots in this algebra lesson. They create a scatter plot from their guesses regarding a famous person’s birth date and the actual birth date then they examine and interpret the results of their graph.

High schoolers explore the concept of exponential growth.  In this exponential growth lesson plan, students manipulate power models with base 2.  High schoolers discuss what would happen if you doubled a penny over the course...

Do women with college degrees get married later? Using a provided scatter plot of the percentage of women who earn bachelor's degrees and the median age at which women first get married over time, pupils conduct a linear regression...

Simulate C-14 decay using M&M and Reese's Pieces candies. In this scatter-plot lesson, young scholars perform an experiment to simulate the half life of C-14. Information is plotted on a scatter-plot. Students answer four...

Students linearize data to determine if an exponential model is suitable. In this linearizing data to determine if an exponential model is suitable lesson, students graph the residuals of sets of data that appear to have an exponential...

Predict the year that college costs will double in your state using linear modeling. The first part of this two-part project based learning activity asks young mathematicians to use data from the College Board. They graph the data,...

Students collect and graph data. In this statistics lesson, students analyze their plotted data using a scatter plot. They identify lines as having positive, negative or no correlation.
