A large part of those who want to learn about Google Analytics, don't have access to a real company account, which is why they find it difficult when they watch or follow trainings, as they cannot immediately apply their knowledge to a real account.
Many of them are not aware that there is a Google Analytics Demo Account, which collects information from the Google Merchant store, where they sell Google related things. This account is real and fully functional and can be experimented with (naturally, with certain limitations). We use this when we're doing our trainings so that all students can observe the same data.
To use this demo account, you need to have or open a Google Analytics Account, and import the demo account into your Google Analytics.
The link and explanation for using this demo account can be found on this link: https://support.google.com/analytics/answer/6367342?hl=en#access
