A positive trend line tells us the scatter plot has a positive correlation. Any ideas on how this could be done? Trend lines are lines used to approximate the general shape of a scatter plot. Then as they change the graph, the r value (correlation coefficient) is changing in the note of the instructions. Here is the idea: Students explore a series of challenges (make the r value between _ and _) with scatterplots that they can adjust on a graph.original and Desmos applied a tiny amount of polish to negative. Scatter plots are an awesome tool for presenting a vast and confusing amount of data and turning it into an easy to digest, comprehensible visual aid for your audience or readers.

With a variety of reasonable choices, students will estimate the correct r value and interpret positive and negative slope, as well as the strength or weakness of the correlation coefficient of a linear fit.This two-sided worksheet comes with an.
