How to approach this question
Consider Lopez's specific goal: to know the popularity of films in *his town* for *his new cinema*. Would general, pre-existing data (secondary) be best, or would data he collects himself from the local population (primary) be more relevant?
Full Answer
Primary.
Reason: The secondary data available (e.g., national data) may not be representative of the specific tastes of people in Northtown. By collecting primary data (e.g., a survey of local people), he can get information tailored to his specific needs.
There are valid arguments for both, but primary data is arguably better for his specific purpose.
**Argument for Primary Data:** Lopez needs to know the preferences of the potential customers for *his new cinema in Northtown*. National data (secondary data) on film popularity might not reflect the specific demographic and tastes of the local population. For example, Northtown might have a large student population or a large population of families with young children, which would affect film preferences. By conducting his own research, such as a survey of local residents (primary data), he can gather information that is directly relevant to his business needs.
**Argument for Secondary Data:** Collecting primary data can be time-consuming and expensive. Using existing data on film popularity from the existing cinema in town or national box office figures (secondary data) would be much quicker and cheaper. It could provide a good general starting point, even if it's not perfectly tailored.
Common mistakes
✗ Ticking a box without providing a reason.
✗ Providing a reason that doesn't relate to the choice between primary and secondary data (e.g., "because he needs to know what films to show").
