Answer:
D. Thursday
Step-by-step explanation:
We judge the accuracy by how close the predicted value was to the actual value. This can be measured by the absolute value of the numbers in the chart. The absolute value of -2 is the lowest, so Thursday's forecast was the most accurate.
Picture the number line. The distance away from the actual forecast was 4, 6, 7, and 2 on these four days. Which is the closest to the actual? Thursday.
