Which of the following is the first step in the multivariate clustering process?

The correct answer is A .

The multivariate store clustering process starts by identifying the Product Demographic Affinity Profile , because the analyst first needs to understand which demographic groups have the strongest relationship or affinity with the product/category being studied. ARC’s category-specific store clustering guidance identifies “Identify the Product Demographic Affinity Profile (PDAP)” as a core step and then moves into calculating product demand potential.

This sequence matters. You cannot calculate demand potential correctly until you understand the demographic profile that is most relevant to the product or category. Once the product’s demographic affinity is known, the analyst can compare that profile to store-level demographic profiles and then create meaningful clusters based on demand and opportunity.

Option B is later in the process because clusters are created after the relevant product and store-level measures are understood. Option C is important, but it follows the product affinity logic. Option D also comes after identifying the demographic affinity profile.
