Question: To understand how many users are coming from various devices, like computers or mobile phones, you run a report that shows this data, per device, over the past 30 days. In this report, which of these is considered a "metric" in Google Analytics?
- The date range setting for the last 30 days
- The device types, desktops and mobile phones
- How many users were on mobile phones
- Where users came from before reaching your site
Explanation
A metric is a quantitative measurement in Google Analytics. User count is a metric because it reports how many users meet a condition in the report. Device type is a dimension because it describes the category used to break down the data. The number of users associated with mobile phones is therefore the measured value, not the descriptive attribute.
Why the other options are incorrect
Where users came from describes acquisition source information, which is a dimension.
Device types are dimension values used to group data, not numerical measurements.
Date range setting controls the reporting period, but it is not a metric.
