Check Your Understanding

1. What is a pattern?

Answer: A pattern is something that repeats or follows a rule. Seasons repeat, school schedules repeat, and even your morning routine follows a pattern.

2. Give an example of a pattern in nature.

Answer: Day and night is a pattern — it repeats every 24 hours. Seasons are a pattern — spring, summer, fall, winter, then spring again.

3. Why are patterns important in data science?

Answer: Because finding patterns in data is how we make predictions and understand the world. If you notice a pattern, you can often predict what comes next.

4. What is the difference between a pattern and a coincidence?

Answer: A pattern repeats reliably — it happens again and again. A coincidence is something that happened once or twice by chance. Data scientists look for patterns, not coincidences.
