Scatter Plots

Curated and Reviewed by Lesson Planet

What's my line, anyway? A video covers the aspects of finding an equation of the best-fit line for a set of data. It works through plotting the points to drawing a line that appears to represent the data. The presenter suggests finding the point-slope form of the line, since it is the easiest to find, and then rewriting it into slope-intercept form.

Instructional Ideas
  • Have the class collect bivariate data from any other source and construct a scatter plot to determine the equation of a best fit line
Classroom Considerations
  • The video mentions that the best-fit line must go through at least two data points; this is not necessarily the case
  • This video is hosted on YouTube
Pros
  • The beginning is a review of scatter plots and the association of data
  • Examples use numbers that do not come out pretty, which is typical for real-world problems
Cons
  • None
