The examples of using secondary data are:
- A hotel chain purchases syndicated panel data to identify demographic trends.
- An electronics manufacturer uses U.S. Census data to create customer profiles.
- A travel company uses the last three years of its sales invoices to determine package deals.
These options clearly involve the use of existing data that has been collected by others (syndicated panel data, U.S. Census data, and sales invoices that the company has already generated).
In contrast:
- A real estate agent uses questionnaires to assess customer satisfaction. (This is primary data since the agent is collecting original data directly from customers.)
- A soft drink company conducts neuromarketing studies to gauge the effectiveness of its advertising. (This is also primary data collection, as it involves original research and studies.)
