Drawing Line Graphs and Best-Fit Lines
Ever shake your head at line graphs drawn by students? Or best-fit lines that don’t really fit? Here is a tutorial movie that explains how to plot data for a line graph, and draw a pretty good best-fit line using a ruler. The movie is posted on the Exploring Physics YouTube channel, and is one of a large number of tutorial movies included in the Exploring Physics Curriculum app. All movies posted on our YouTube channel are free for your use and can be used at a variety of grade levels, from middle to high school.
