Check Your Understanding

1. What is raw data?

Answer: Raw data is information that has not been organized yet — like a list of scribbled survey answers or a pile of measurements with no order.

2. Why is messy data hard to use?

Answer: Because you cannot see patterns, count totals, or compare groups when information is jumbled. Organization makes patterns visible.

3. What is a data table?

Answer: A data table has rows (horizontal lines) and columns (vertical lines) with headers that label what each column contains. It is the most basic way to organize data.

4. What goes in the rows and what goes in the columns?

Answer: Each row is usually one person or one observation. Each column is one type of information (name, age, answer to question 1, answer to question 2, etc.).
