Tables:

1. Make sure to look at the entire table or graph.
2. Make sure to express your answer in the correct units (Units of the Tables or Graphs).
3. Look at the possible answers before calculating.
4. Don’t confuse decimals and percentages. If the units are percentages, then an entry of .2 means .2% which is equal to .002.
5. In inference questions, only the information given can be used. See if the answer makes sense.

The table below gives the height and weight of 11 newborn infants.

Q. What is the difference in weight between the tallest and shortest infants?

(a) 13 pounds (a) 12.1 pounds
(c) 8.8 pounds (d) 6.9 pounds
The correct answer is (c), which is obtained by subtracting 3.3 (the weight of the shortest–10 inches–infant) from 12.1 (the weight of the tallest–23 inches–infant).
