Correlation Coefficients
This page provides a good discussion of correlation coefficients (r,) which indicate the "strength of the linear association between variables." Includes formulas and scatter plots. Some prior knowledge of statistics might be helpful.

Texas Instruments: Numb3 Rs: "Take Out" Outliers
Based off of the hit television show NUMB3RS, this lesson has students create box-and-whisker plots for given data, and then determine which (if any) data points are outliers. Students determine outliers through two methods in this...

Khan Academy: Linear Regression Review
Linear regression is a process of drawing a line through data in a scatter plot. The line summarizes the data, which is useful when making predictions.
Khan Academy
Khan Academy: Correlation Coefficient Review
The correlation coefficient r measures the direction and strength of a linear relationship. Calculating r is pretty complex, so we usually rely on technology for the computations. We focus on understanding what r says about a scatterplot.

Nearpod: Scatterplots, Correlation & Lines of Best Fit
In this lesson on scatterplots, young scholars will learn how to create the line of best fit and analyze scatterplots by learning about correlations and causation.
Texas Instruments
Texas Instruments: Math Today for Ti Navigator System Cropland Value Grows
Students will create a scatter plot for the data in the USA TODAY Snapshot, "Cropland value grows," and identify the independent and dependent variables for the data. The students will find the rate of change for the data and label this...
US Geological Survey
Usgs: Water Quality of San Francisco Bay
This resource from the United State Geological Survey provides data about San Francisco Bay's water quality. Data is displayed in time series plots, vertical profiles, longitudinal sections, space and time contours, and x-y scatter plots.

Texas Instruments: Numb3 Rs: Exponential Modeling
Based off of the hit television show NUMB3RS, this lesson introduces students to exponential equations, their graphs, and their application in the real world. The lesson is framed in the context of the number of cell phone users for a...
Texas Instruments
Texas Instruments: Two Hot, Two Cold
In this activity, students collect both Celsius and Fahrenheit temperature data for several water samples of varying temperatures. They use the data to find a conversion equation that will calculate the Fahrenheit temperature for any...
Texas Instruments
Texas Instruments: Exploring the Pythagorean Theorem and Its Applications
Students discover the Pythagorean Theorem by exploring right triangles using Cabri Jr. They apply the Pythagorean Theorem to real-world problems. Also, students create a scatter plot of the data and find an equation that fits the data.
Texas Instruments
Texas Instruments: Beverage Tests
In this activity, students determine the pH of liquid samples. They get familiar with the pH scale, create graphs comparing pH levels, and compare data displayed as a scatter plot, a boxplot, a histogram, and a bar graph.

Texas Instruments: Numb3 Rs: Prime Time
Based off of the hit television show NUMB3RS, this lesson helps students understand the Goldbach Conjecture (any even number greater than four can be written as the sum of two odd prime integers). Students explore how many pairs of odd...
Science Education Resource Center at Carleton College
Serc: Average Rates of Change and Trend Lines
In this Spreadsheets Across the Curriculum activity, students calculate the average rate of change and graph a scatter plot of status high school dropout rate for 1975-2002. The module combines interpretation of rate of change in the...
Texas Instruments
Texas Instruments: The Normal Distribution
Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.
