Is there a correlation between the number of cats you own and your age? Use a scatter plot to analyze these correlation questions. Learners plot data and look for positive, negative, or no correlation, then create stem-and-leaf plots to...

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Pupils use the provided census data to guess the future height of a child. They organize and plot the data, solve for the line of best fit, and determine the likely height and range for a specific age. 

Given scatterplots that represent problem situations, the student will determine if the data has strong vs weak correlation as well as positive, negative, or no correlation.

Given a set of data, the student will be able to generate a scatterplot, determine whether the data are linear or non-linear, describe an association between the two variables, and use a trend line to make predictions for data with a...

A scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose x-y coordinates relates to its values for the two variables.

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

Match correlation coefficients to scatterplots to build a deeper intuition behind correlation coefficients. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Help Jane sell her Forrester! Using the data given, students will make an appropriate plot with well-labeled axes that would allow you to see if there is a relationship between price and age and between price and mileage. Students are...

Practice plotting points to construct a scatter plot. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

A good scatter plot has the independent variable on the x-axis and the dependent variable on the y-axis. Also, the scale of both axes should be reasonable, making the data as easy to read as possible. In these practice problems, we...

Given a scatter plot, can you estimate the slope of the line of best fit that goes through the data points? Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Practice explaining the meaning of slope and y-intercept for lines of best fit on scatter plots. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.
