Select “Adjust trend,” and complete the following.

  1. Move the slider from “No trend” to “Positive trend,” and pay attention to the scatterplot. What do you notice? At what point on the slider is there a correlation, and when is there no correlation?
  2. Move the slider from “No trend” to “Negative trend,” and pay attention to the scatterplot. What do you notice? Again, at what point on the slider is there a correlation, and when is there no correlation?

You should notice the following:

  • There is still no correlation at the “No trend” point of the slider.
  • As you move the slider from “No trend” to “Negative trend,” the correlation becomes stronger.
  • Recall that the correlation also became stronger when the slider was moved from “No Trend” to “Positive Trend.”

You should notice the following:

  • At the “No trend” starting point, there is no correlation.
  • As you move the slider from “No trend” to “Positive trend,” the correlation becomes stronger.
