D175: Consumer Behavior

A study guide to WGU's D175, the marketing major course on why consumers buy, covering the decision process and the internal and external influences behind it.

Updated October 2026 · 5 min read

D175 asks a simple question with complicated answers: why do people buy what they buy? It follows Marketing Management in WGU's BS Business Administration, Marketing major.

WGU's program guide describes the course as a study of buying behavior, consumer behavior theories and the consumer decision-making process. It draws on psychology, sociology, anthropology and economics to explain and predict what consumers do.

Students often know the theories but struggle to apply them. The competencies ask you to use consumer influences to develop marketing strategy for a specific target market.

Key Concepts Explained

The Consumer Decision Process

A common model has five stages: need recognition, information search, evaluation of alternatives, purchase and post-purchase behavior. Marketers ask where their customers hesitate and design tactics for that stage.

Internal Influences

Motivation theories such as Maslow's hierarchy explain which need a product meets. Perception explains why two people read the same advert differently. Learning explains how habits and brand loyalty form through repeated rewards.

Example: A fitness app targets first-time runners. Their need is confidence as well as health (motivation). Many fear looking inexperienced (personality and perception). The strategy: beginner-only plans, encouraging push notifications that reward small wins (learning), and in-app groups of runners at the same level.

External Influences

Reference groups set what feels normal, families share decisions on larger purchases, and culture shapes values, rituals and taboos. A strategy for a family car, for example, must address several decision makers, not one.

How Marketers Gain Consumer Insight

WGU's course description stresses an interdisciplinary perspective. Each discipline contributes a different lens:

DisciplineWhat it explains
PsychologyMotivation, perception, learning, attitudes
SociologyGroups, social class, family roles
AnthropologyCulture, rituals, symbols and meaning
EconomicsIncome, prices and trade-offs in choices

Insight comes from research. Surveys measure attitudes across many people, interviews and focus groups explore reasons in depth, and observation shows what people actually do, which can differ from what they say. Purchase and website data reveal real behavior at scale.

A good insight is specific and actionable, for example: "first-time buyers abandon checkout when delivery costs appear late". It points directly to a marketing response.

Where Students Get Stuck

Where D175 Fits in the Program

In WGU's standard path, Consumer Behavior comes after Marketing Management and before Digital Marketing and Content Marketing. It adds the customer's point of view to the planning framework you built in D174.

The insights you develop here are reused later. Content Marketing depends on understanding audience needs, Brand Management relies on how consumers form associations, and the capstone asks you to make decisions about buyer behavior using data. Good D175 notes save time in every one of those courses.
