Students convert degrees between two different units. In this algebra lesson, students graph linear equations and identify the line of best fit. They use their line of best fit to make predictions given a set of data.
Students graph an equation and analyze the data. In this algebra lesson, students graph scatter plots and identify the line of best fit using positive correlation, negative correlation an d no correlation. They apply their data analysis to word problems.
Learners work in pairs to test the strength of spaghetti strands. They collect and graph data to determine a line of best fit. Students create a linear equation to interpret their data. Based on the data collected, learners predict results with 10 strands of spaghetti.
Eleventh graders explore coefficient of correlation for bivariate data. Through activities, 11th graders use spaghetti to demonstrate the use of scatter plots and estimating a line of best fit. After collecting information, pupils use calculators to plot ordered pairs on a coordinate plane. Classmates observe the relationship between two items.
Ninth graders explore the concepts correlation studies.  In this correlation studies instructional activity, 9th graders research for correlation studies.  Students take a given data set and determine the line of best fit by making a scatter plot.  Students discuss how certain events are correlated.
Students investigate different correlations. In this algebra lesson, students analyze graphs and identify the lines as having positive, negative or no correlation. They calculate the line of best fit using a scatter plot.
Students investigate and analyze data. In this algebra lesson, students plot data on a coordinate plane and identify the line of best fit. They plot points correctly and make predictions about their data. 
Pupils calculate the length, width, height, perimeter, area, volume, surface area, angle measures or sums of angle measures of common geometric figures. They create an equation of a line of best fit from a set of ordered pairs or set of data points. They interpolate and extrapolate to solve problems using systems of numbers.
Middle schoolers model linear data in a variety of seings. They construct scatterplots, interpret data points and trends and investigate the line of best fit.
In this least squares approximation activity, students determine the number of solutions a given linear system has. They find the least square error and the equation of a line of best fit for a set of three points. Students find the equation of a parabola of best fit through a given set of points.
Learners conduct surveys and collect data. They analyze the data through graphs and calculate the rate of change. Students write an equation that represents the line of best fit. They determine the points on a line. Learners participate in real world activities.
Students investigate reaction rates.  For this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns determin the line of best fit and relate slope to rate of change.
Learners collect and analyze data. In this statistics instructional activity, students plot their data on a coordinate plane. They identify the line of best fit the type of correlation as positive negative or no correlation.
Students graph and analyze data. For this algebra lesson, students relate algebra to their engineering class. They analyze a set of given points, write an equation for the line and make predictions. They find the line of best fit.
Students, in groups, work together to determine the relationship of the distance a projector is from a screen and the size of image that results. While experimenting with the data, students identify the independent and dependent variable and write the equation of a line of best fit. They determine the best distance for the projector to illuminate the image on the entire screen.
In this line of best fit worksheet, students solve and complete 8 different problems that include plotting and creating their own lines of best fit on a graph. First, they study the samples at the top and plot the ordered pairs given on the graph to the right. Then, students respond to the questions that follow using their graph and information to help them.
In this Algebra I/Algebra II worksheet, students determine the line of best fit for a scatter plot and use the information to make predictions involving interpolation or extrapolation.  The one page worksheet contains one multiple choice question.  Answers are included. 
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 lesson, 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.
Eighth graders investigate using scatter plots to illustrate the data found in sets. Then they connect the coordinate points in order to find the correct line. Students make estimations of the second variable when given the first. They work in small groups in order to prepare for an assessment.
In this scatter plots and line of best fit worksheet, students create scatter plots from given sets of data. They answer questions concerning the scatter plot. Students write the equation of a line, identify the type of correlation depicted in a graph, and draw the line of best fit. This one-page worksheet contains ten problems.
