1. scatter plot
The pattern looks like ___________
• A random dispersal of points
• A straight line
• A parabola
• A sine wave
• A circular patch of points
• A shapeless clump of points
• Dense points on the left grading to sparse points on the right


add as many details as you can. Perhaps you can write:
• “The pattern looks like a straight line, beginning at the data point (1, 13) and ending at the data point (7, 3). One data point, (3, 12), is farther from this line than any of the other 24 data points.”


• “The pattern looks like one clump of points.”
You might be able to write:
• “The patterns appears to be a roughly spherical cluster of data points, centered
at approximately (50, 29). Specifically, all the data points are contained within a
circle centered at (50, 29) with a radius of 18 graph units, and, to my eye, the data
points appear fairly uniformly distributed within this circular area.”
