Spotting Trends

Scientists use data to predict what will happen next. On the ACT Science section, you’ll often interpret trends and make predictions based on patterns.

How to Read Trends

• Upwards/Downwards Movement: Identify if the data is increasing or decreasing.
• Plateaus: Watch for places where values stay the same.
• Anomalies: Notice points that don’t fit the general pattern.

Making Predictions

Use the trend to guess what might happen if conditions change. This skill is similar to predicting tomorrow's weather by looking at a week's worth of data.

Practice Questions

• If the temperature keeps rising, what will it be in two hours?
• If a pattern holds, what will happen when a new variable is introduced?

Real-World Use

From predicting stock prices to planning crop harvests, spotting trends is vital!
