A city government wants to analyze traffic patterns to improve public transportation. They need a dataset that is freely available and covers multiple years of traffic counts. Which source should they use?

The city's open data portal, which publishes traffic sensor counts

A commercial data vendor that sells traffic data

A private dataset from a ride-sharing company

A synthetic dataset generated from a traffic simulation model

A researcher needs to access a dataset of global climate measurements for a study. They want a source that is openly accessible and regularly updated. Which source should they use?

A government agency's open data portal

A commercial data subscription service

A private dataset from a research lab

A synthetic dataset generated from a climate model

How does synthetic data differ from generated data?

Synthetic data is collected from sensors, while generated data is created by AI models

Synthetic data is always structured, while generated data is always unstructured

Synthetic data is always public, while generated data is always private

Synthetic data is artificially created to mimic real data, while generated data is a byproduct of system operations

An e-commerce company wants to test a new recommendation system. They need a dataset that mimics user browsing behavior but does not contain any real user data. Which approach should they take?

Use a small sample of real user data and duplicate it.

Collect real user data and anonymize it by removing personal identifiers.

Generate synthetic user sessions using a probabilistic model of browsing patterns.

Use a public dataset of web browsing logs.
