You can use a scatterplot to estimate a value between two known values. Estimate the world production of oil when the United States produced 12% of the worlds

oppturf

Step 1
Scatterplot World Oil
Production is on thehorizontal axis and U.S. Percent of World Oil Production is on the vertical axis. The World Oil Production ranges from 7 to 21, thus an appropriate scale for the horizontal axis is from 0 to 22. The U.S.
Percent of World Oil Production ranges from 45.9 to 72.5, thus an appropriate scale for the vertical axis is from 30 to 80.

Step 2
We draw a horizontal line at 12% until we arrive at the location where we expect the new point to fit in the pattern. Next, we draw a vertical line through this expected new point. We note then note that this vertical line intersects the horizontal axis at approximately 62 and thus the estimated world production of oil when the United States produced 12% of the world’s oil is expect to be 62 billion barrels. Result: 62 billion barrels.
