How Do You Use a Scatter Plot to Find a Line of Fit?

Young mathematicians construct and analyze patterns of association in bivariate data using scatter plots and linear models. The sixth chapter of a 10-part eighth grade workbook series then prompts class members to construct and...

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....

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

Analyze data using technology. Middle schoolers design data investigations, describe data, and draw their own conclusions. Then they select the best type of graph, graph and interpret the data, and look for patterns in trends. They also...

Sal trades his tablet for an Excel spreadsheet in this video, which covers fitting data to a line. Using a word problem about median income, he not only solves the problem but also demonstrates how to use scatter plots and Excel tools in...

Learners explore the concept of univariate and bivariate data. In this univaritate and bivariate data lesson, pupils discuss the differences between univariate and bivariate data. They work sample problems where they must construct box...

How do you determine the correlation in a set of data? Plot the data, find the line of fit, then use that line to determine if the correlation is positive, negative, or no correlation. This tutorial demonstrates that when a line of fit...

You can use a scatter plot to determine if there is a positive, negative, or no correlation between the given data. After graphing data you need to find a line of fit, a line that best represents the data you've graphed. It will be the...

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...

The class explores a real-world application in which the data represents rental prices of beach condos. They problem solve by multiplying matrices to determine the cost of each property in each season. Several scenarios are presented in...
