Interpreting Data

There are three levels of graph comprehension:

Reading the Data: This requires no interpretation of the graph. You literally read what is displayed.
Example: There are 20 McIntosh Apples in the store.

Reading Between the Data: This requires interpretation of the mathematical relationships expressed in the graph. Quantities are compared and other mathematical concepts (such as addition and subtraction) are applied.
Example: There are 15 more Red Rome apples than Golden Delicious apples.

Reading Beyond the Data: This involves making inferences about the data. Our schema (background knowledge) is used to make conclusions that are not explicitly stated in the graph.
Example: McIntosh apples must be the most popular type of apple because there are the least amount of those on the shelf, meaning most people probably buy that type of apple.

In Grade Three we want to be able to move away from just reading the data and work towards reading between and beyond the data. This requires us to apply critical thinking skills and to think "outside of the box."
