7 Questions

  1. Make a scatter plot of the data.
  2. Draw an appropriate trend line,
  3. Write an equation of the trend line.
Be sure to include relevant graph detail: label axes, indicate units and scale on both axes, and use arrows to represent end behavior, as appropriate.

Vocabulary: Given a set of data pairs, how would you decide whether to use interpolation or extrapolation to find a certain value?

Compare and Contrast How are a trend line and the line of best fit for a set of data pairs similar? How are they different?

Error Analysis: Refer to the table. A classmate says that the data have a negative correlation because as x decreases, y also decreases. What is his error?
