1.

  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.

2.

Consider your scatter plot and the data in the previous item. What type of relationship is shown?

S.ID.6.a
S.ID.7
3.

Consider your scatter plot and the data once more. Predict the average maximum daily temperature in January at a latitude of 50° N.
Choose the most reasonable prediction.

F.LE.5
4.

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

5.

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?

6.

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?
