Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the data representation?Discrete or continuous values, numbers, characters, or symbols
2. What is the data collection methods?Measurement, observation, query, controlled experiments, and in-situ environments
3. Why do we need to clean data before using it?Cleaning data fixes mistakes and removes odd numbers that don’t fit. This makes sure the results we get are trustworthy and not wrong because of bad data.
4. How do computers help with big data?Computers can look at huge amounts of data very fast. They use special tools like machine learning to find patterns that people can’t see by hand.

Discrete Data: Data that can only take specific, separate values, like whole numbers.
Continuous Data: Data that can take any value within a given range, like temperature.
Big Data: Extremely large datasets that require advanced analytical tools to process.
Machine Learning: A type of artificial intelligence that allows systems to learn from data without explicit programming.
