[Free Registration/Login may be required to access all resource tools.] This Concept introdices scatterplots and linear correlation for bivariate data.

Use examples to determine and explain the linear correlation of independent and dependent variables.

An interactive program where students will explore regression lines. Students will be introduced to the correlation coefficient and come to understand what it represents through the given exploration. Requires Java.

[Free Registration/Login may be required to access all resource tools.] This Concept introduces students to testing a claim about linear regression.

[Free Registration/Login may be required to access all resource tools.] Use a calculator to create a scatter plot and to determine the equation of the line of best fit.

The online assessment displays knowledge of concepts used in Algebra I. The multiple choice questions test learners on analyzing linear equations. Topics include calculating the equation of a line and interpreting correlation.

Explains, with examples, what scatter plots are and how to interpret the data. Discusses trends, interpolation and extrapolation, and correlation. Includes a set of practice questions.

This activity is designed to help students work with linear regression models, error, correlation coefficients and coefficients of determination. In this activity students not only deal with the mathematical concepts of regression but...

Students can use lists of data and the correlation factor of various regressions to determine the best regression line.

A CSI activity that deals with "TRENDS IN DATA". You'll conduct an investigation whereby you'll measure parts of your body and contribute to the investigation data to solve a murder. You'll look at different relationships to find proper...

In Spanish. This interactive unit shows you the statistical relationship between two variables.

Create your own scatter plot or use real-world data and try to fit a line to it. Explore how individual data points affect the correlation coefficient and best-fit line.

Students explore the relationship between two quantitative variables in bivariate data using various x-y plots. They compare the relationships for several categories on the same plot. Students calculate the correlation coefficient to...

Students graph scatter plots and understand the concepts of correlation and least-squares regression. They also perform transformations to achieve linearity in the data plot.

[Free Registration/Login Required] This lesson is a discovery lesson where the students have to create a scattered plot and find a linear correlation that approximates the golden ratio.

Dozens of statistical terms are defined and illustrated in this glossary.

This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the...
