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...

Solve equations and graph systems of inequalities. Designed as a lesson to reinforce these concepts, learners revisit shading and boundaries along with solving linear inequalities.

For this functions worksheet, high schoolers solve 40 short answer problems. Students determine if a graph represents a function. High schoolers find the domain of absolute value and square root functions.

Use measures of variance to compare and analyze data sets. Pupils match histograms of data sets to their respective statistical measures. They then use calculated statistics to further analyze groups of data and use the results to make...

Discuss different sources of energy and how much greenhouse gas each might emit. The six sources are then ranked according to emissions from greatest to least. Finally, the true cumulative emissions are revealed to show the class how...

A cross-curricular resource that takes the electoral votes and allows your learners to organize and analyze the data. Young voters can determine which states are more influential and interpret the dotplot provided for more data....

In the second lesson of a five-part series, young climatologists use provided temperature and precipitation data to create climographs of three different cities. They then analyze these climographs to develop a general understanding...

Students collect data and graph their results, then analyze the graphs. In this geometry lesson, students examine slopes and their graphs and discuss the relationship between the lines and the slopes.

Fifth graders complete a series of graphs by gathering information and using Excel to graph the information.  In this graphing lesson, 5th graders graph favorite desserts of the class. Student put their results into the...

Students explore change represented in graphs comparing distance and time. They exchange and share their graphs. Students interpret and create distance versus time line-graphs, and write stories based on these graphs. They interpret a...

Students analyze graphs to determine relationships between variables and rates of change. They determine the basic concepts about static reaction forces. They determine the slope and equation of a line.

Learners collect, graph and analyze data. In this statistics lesson, students use circle, pie, bar and lines to represent data. They analyze the data and make predictions bases on the scatter plots created.

Fifth graders collect temperature readings over a period of time, enter the information into a spreadsheet and choose the appropriate graph to display the results.

Fifth graders evaluate data from a circle graph that compares time spent on various activities. They use the computer to manipulate their own data as they compare, examine, create and evaluate data using circle graphs.

Learners graph their linear equations. For this algebra lesson, students examine their lines and relate it to the slope or rate of change. They relate the steepness of the line to the slope being positive, negative or zero.

The bounce of a golf ball changes the result in golf, mini golf—and a great math activity. Scholars graph the height of golf ball bounces before finding a line of best fit. They analyze their own data and the results of others to better...

How do doctors predict a child's future height? Scholars use one case study to determine the height of a child two years into the future. They graph the given data, determine the line of best fit, and use that to estimate the height in...

Discover the relationship between tangent lines and the tangent function. Class members develop the idea of the tangent function using the unit circle. They create tables of values and explore the domain, range, and end behavior of...

Investigate the relationship between height and arm span. Young statisticians measure the heights and arm spans of each class member and create a scatter plot using the data. They draw a line of best fit and use its slope to explain the...

Mississippi has both the highest obesity and poverty rate in the US. Does the rest of the data show a correlation between the poverty and obesity rate in a state? Learners tackle this question as they practice their skills of regression....

Students practice plotting functions on the Cartesian coordinate plane, see several categories of functions, including lines and parabolas, and read a graph, answering questions about the situation described by the graph

Students determine if there is an associationm in a scatter plot of data. They analyze data through predictios, comparisons, and applications. Students calculate the line of best fit using a graphing calculator. They display data in...

Students explore the concept of graphing stations.  In this graphing stations lesson, students head to various teacher set-up stations involving slope, point-slope, standard form, parallel lines, etc.  Students work problems at...

Students explore the concept of line of best fit. In this line of best fit lesson, students find lines of best fit in examples about riding your bike home from school and dentistry. Students find two data points and find the line of best...
