A comparison graph uses different scales for two groups without clearly stating this. What will happen?

Answer and explanation

Correct answer: The visual comparison may become misleading

The governing concept is fair and transparent scale selection in data visualization. If two groups use different unstated scales, bars or plotted heights may look similar or different for reasons that do not match their actual values. This can cause viewers to overestimate one group or underestimate another. Option D is correct. Stating a common scale, or clearly labelling separate scales when necessary, is essential; colour or title changes cannot repair hidden scale differences.
