Data Interpretation — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The graph show 12 books.
Corrected: The graph shows 12 books.
A singular subject like graph takes the singular verb shows in the present tense.
2. Fix the sentence:
The bars is taller for Monday.
Corrected: The bar is taller for Monday.
Use the singular noun bar with the singular verb is to keep subject and verb agreement.
3. Fix the sentence:
Each axis have a label.
Corrected: Each axis has a label.
Each is treated as singular, so the verb must be has, not have, in this sentence.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The title of a bar graph tells you the topic of the data shown.
The title names the topic, telling readers what information the bars on the graph represent.
2. On a bar graph, the vertical line is called the y axis.
The vertical line is the y-axis, and it usually shows the scale of values being measured.
3. The numbers along the side of a bar graph show the scale used.
The scale tells you the equal interval between numbers so you can read each bars height.
4. If a bar reaches up to 25, the value for that category is 25.
Reading across from the top of the bar to the y-axis gives the exact value, which is 25.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. What three parts should every bar graph include so readers can understand it?
Sample answer: Every bar graph should include a clear title, labeled axes, and a numbered scale so readers know the topic and values.
Title, axis labels, and scale work together to make a bar graph easy to read and understand.
2. How do you find the value of a bar on a bar graph?
Sample answer: Look at the top of the bar, then trace a straight line across to the scale on the y-axis to read the value.
Tracing horizontally from the top of the bar to the scale gives an accurate value for that category.
