Baseball Relationships - Using 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...

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...

Is there another way to view whether the data is linear or not? Class members work alone and in pairs to create scatter plots in order to determine whether there is a linear pattern or not. The exit ticket provides a quick way to...

More than just data, scatter plots are full of information that can be used to answer a variety of questions. This lesson uses a plot with information about bird egg sizes to answer questions about the relationship between length and...

High schoolers 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.  High schoolers make...

What do your classes know about statistics? Use a pre-test to determine their background.  Topics include scatter plots and lines of best fit, two-way frequency tables, and modeling with linear equations.

Discover how trend lines can be useful in understanding relationships between variables with a lesson that covers how to informally fit a trend line to model a relationship given in a scatter plot. Scholars use the trend line to make...

Scholars learn to create scatter plots and investigate any relationships that exists between the variables with a lesson that also show them that statistical relationships do not necessarily indicate a cause-and-effect relationship. 

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 calculating it.

Scatter plots are a great way to connect data with a visual model. Learners look at wages earned depending on education level and determine if there is a correlation between the two. The worksheet includes short answers they must discuss...
