A local cinema asks customers for their postcode when they purchase tickets - HSC - SSCE Business Studies - Question 15 - 2007 - Paper 1

The process described in the question involves collecting information directly from customers at the point of sale, which represents the collection of data specifically for a particular purpose—here, for planning a marketing campaign.

This falls under the category of Primary data collection because the cinema is directly gathering new data from its customers (the postcodes) for the first time, rather than analyzing existing data (which would be secondary data). Thus, the correct answer is (C) Primary data collection.
