Final answer:
Dimensions in website analytics represent different aspects of data that can be used to segment visitor information, such as region. Metrics like screen resolution, bounce rate, and % new visits quantify user interactions but are not dimensions themselves.
Step-by-step explanation:
Understanding Website Analytics
When analyzing website traffic and user behavior, 'dimensions' are the different aspects of data that can be used to segment and understand how visitors interact with a website. For example, region refers to the geographical location from which a user accesses a website and can be an important factor in understanding and targeting audiences. On the other hand, metrics such as screen resolution, bounce rate, and % new visits quantify user interactions. Screen resolution details the display attributes of the visitor's device, bounce rate indicates the percentage of single-page visits, and % new visits shows the proportion of first-time visitors to a site. While metrics provide quantitative values, dimensions help to contextualize this data, making them arguably the categories or descriptors within analytics.
