Kuta Software-Infinite Pre-Algebra Scatter Plots - Worksheet - Correlation and Scatter Plot Practice

Oct 8, 2026

Kuta Software-Infinite Pre-Algebra worksheet on scatter plots and correlation analysis. Students examine given (X, Y) data sets to determine whether the points show positive correlation, negative correlation, or no correlation, and whether the relationship is linear or nonlinear. The activities include constructing scatter plots, classifying the trend, and finding the slope-intercept form of the best-fit line for selected data.

FAQs

How do you decide whether the data shows positive, negative, or no correlation?

Look at the overall direction of the points in the scatter plot: an upward trend suggests positive correlation, a downward trend suggests negative correlation, and no clear trend suggests no correlation.

What does it mean when the relationship is linear versus nonlinear?

Linear relationships follow a roughly straight-line pattern, while nonlinear relationships follow a curved or irregular pattern rather than a straight line.

What is the slope-intercept form and when is it used here?

The slope-intercept form expresses the line of best fit as y = mx + b. It is used when the worksheet asks for the equation of a line that best fits the given data.
