Which option is a metric example?

• A. City
• B. Event count
• C. User type
• D. Traffic source

Answer: (B)

Metrics are numeric measurements that quantify outcomes, while dimensions describe attributes used to segment or group those measurements. Event count is a metric because it represents a numeric tally of how many events occurred. You can aggregate it, compare it over time, or across dimensions to see trends. The other options describe attributes: city is a geographic attribute, traffic source is where visitors came from, and user type is a category of users. These are dimensions you would use to slice data, not measure quantities themselves. So the best example of a metric here is the event count.
