Convert a table into a bar graph

The same survey of favorite fruit is shown both as a table and as a bar graph. The table says apples 3 and bananas 8, and the bar graph shows an apple bar of 3 and a banana bar of 8. Use each representation to fill in what is missing in the other so both are complete.

How to solve
Strategy Organize Information in More Ways — A table and a bar graph are two views of the same data. We translate between the two representations so each missing slot copies its partner's value.
1STEP 1

Read the graph to fill the table

The apple bar rises to 3 and the banana bar rises to 8, so the table values are apples 3 and bananas 8.

apple bar = 3, banana bar = 8
2STEP 2

Read the table to fill the graph

The table lists apples 3 and bananas 8, so the apple bar is drawn to 3 and the banana bar to 8.

3 (apple), 8 (banana)
3STEP 3

Confirm they match

Both views now agree: apples are 3 and bananas are 8 in the table and in the graph.

3 = 3, 8 = 8
Answer
Apples = 3 and bananas = 8 in both the table and the bar graph
Both bars sit on the 0-5-10 scale (3 is below the 5 line, 8 is between 5 and 10), and the table and graph agree, so the completed pair is consistent.
Takeaway

This only needs Grade 3 graph reading: a table number and its bar are the same fact in two outfits!

  • Read the graph to fill the table
  • Read the table to fill the graph
