Primary vs Secondary Data Study Guide

What It Is

Primary data is original, firsthand information collected by a marketer or researcher for a specific purpose. This data is crucial in marketing as it allows businesses to make informed decisions based on their unique needs. For instance, Apple collects primary data through customer surveys to understand their preferences and improve their products. This data helps Apple stay ahead of the competition and maintain its market share.
