Check Your Understanding

1. How do you use a trend to make a prediction?

Answer: If the data has been steadily increasing, you might predict it will continue to increase. Extend the line forward as a guess — but know it is only a guess.

2. Why are predictions not guarantees?

Answer: Because trends can change due to unexpected events, seasonal shifts, or human decisions. A stock that went up for 6 months could suddenly drop.

3. What might break a trend?

Answer: Sudden events (storms, pandemics), seasonal changes (summer to winter), policy changes (new laws), or reaching a natural limit.

4. What is the difference between a prediction and a guess?

Answer: A prediction is based on data and patterns. A guess has no evidence behind it. Predictions can still be wrong, but they are more informed than guesses.
