Draw the line of best fit on a scatter plot.
Clarifications:

Essential Understandings

Concrete:

  • Draw a line between two points on a graph.
  • Identify when data points are close together or spread out.

    Individual data plots are placed on a graph that are not in one perfect line, although a line is drawn to show general direction the data is trending. Some data plots deviate off the line a little. This scatter plot shows a positive linear association.
  • Use appropriate manipulatives (uncooked spaghetti noodle, clear ruler, popsicle stick, etc.) to approximate the line of best fit.
Representation:
  • Understand the following concepts and vocabulary: best fit line, variable, outliers, box plot, scatter plots, data points.
  • Given three choices, select the line of best fit.
General Information
Number: MAFS.8.SP.1.AP.2a
Category: Access Points
Date Adopted or Revised: 06/14
Cluster: Investigate patterns of association in bivariate data. (Supporting Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
