Ask a graph a question its data can answer
Ask a precise question and use the scale to justify the response.
Invite one statement supported by the displayed values and one question the chart cannot settle. This makes interpretation more than naming the largest category and introduces the limits of the information collected.
Identify what the graph records. Compare two named categories. Support the comparison with numbers.
A category with six responses exceeds one with four by two responses, if the key confirms those counts.
A chart describes data, not every cause
Use the displayed data to support the statement and retain its scope. The chart cannot explain causes it did not measure.
A taller bar does not explain why the pattern occurred.
Is the explanation supported by recorded data? Read labels aloud and compare only two categories.
