When analyzing a temperature line graph, which feature would indicate an irregular pattern rather than a clear trend?

• A. Frequent, uneven fluctuations year to year.
• B. A smooth, steady rise.
• C. A steady fall.
• D. Constant values.

Answer: (A)

When reading a temperature line graph, the key idea is to spot how data moves over time. An irregular pattern shows frequent, uneven fluctuations year to year, meaning temperatures bounce up and down without settling into a single direction. This kind of jagged, unpredictable movement stands in contrast to a clear trend, where the data rises smoothly, falls steadily, or stays constant. A smooth, steady rise points to a consistent upward trend, a steady fall to a consistent downward trend, and constant values indicate no change at all. These shapes reflect orderly patterns, not irregular volatility. So the feature that signals an irregular pattern is the frequent, uneven fluctuations year to year.
