Study Notes
Two Types of Statistics
- Descriptive Statistics: Describes data features statistically.
- Inferential Statistics: Draws inferences about a large population from a sample.
Sampling
- Sample: Data available to researchers, a subset of the population.
- Population: All possible observations researchers want to conclude about.
- Key elements of samples: Represent larger populations, selected via a defined process, statistically valid, and representative of population characteristics.
Key Theory
- Simple Random Sampling: Every population member has an equal chance of selection.
- Stratified Sampling: Dividing the population into subgroups (strata) before random sampling.
- Snowball Sampling: Current participants recruit future participants.
- Convenience Sampling: Participants selected based on researcher access and availability.
Issues of Convenience Sampling
- Self-selection
- Non-representative sub-populations (e.g., WEIRD)
Central Limit Theorem (CLT)
- Sample means approximate a normal distribution as sample size increases.
- Larger samples are more reliable than smaller ones.
- The normal distribution is a basis for statistical tests & confidence intervals.
- A sample size of 30 or more often suffices for the CLT.
Law of Large Numbers
- Sample statistics get closer to population values as sample size increases.
- This leads to: More stable estimates, reduced outlier impact, better population representation, and more reliable decisions.
Confidence Interval
- A 95% Confidence Interval (CI) is a range derived from sample data with a 95% chance of encompassing the true population value.
Questionnaire
- Step 1: Define research goals (question, hypothesis, variables).
- Step 2: Identify data needs, operationalize constructs, choose measurement methods.
- Step 3: Analyze data using appropriate data analysis skills.
- Step 4: Decide on questionnaire elements for data collection. Consider advantages (e.g., cheap, quick, adaptable) and disadvantages (e.g., non-engagement, lying, misunderstanding).
- Questionnaire Flow: Start with consent/instructions, then main questions, then easier questions, and finally demographics/feedback.
-
Types of questions:
- Open-ended: Answers with sentences, lists, stories.
- Closed-ended: Limited answer options, quick responses. Includes multi-choice, multi-select, ranking, rating, scales, and matrix tables.
Tutorial 6: The Consumer Decision Journey (CDJ)
- Court (2019): Discusses the shift from a linear funnel model to a dynamic circular CDJ. Key stages are initial consideration, active evaluation, purchase, and postpurchase.
- Traditional Funnel Models: Consumers narrow options for purchase linearly.
- CDJ: A dynamic circular process impacted by various touchpoints and consumer behaviors. Includes stages like awareness, familiarity, consideration, purchase, and loyalty.
Key Phases in CDJ
- Initial Consideration: Impressions from ads, conversations, experiences form a shortlist of brands. Brands in the initial consideration set are more likely to be purchased.
- Active Evaluation: Deeper research and comparison of brand options. This stage is influenced by reviews and word-of-mouth.
- Moment of Purchase: The final decision made based on accumulated information and personal preferences.
- Postpurchase Phase: Personal experience following purchase affects future loyalty and potential brand advocacy. Positive experiences can reinforce loyalty while negative ones can attract competitors.
Types of Loyalty
- Active Loyalty: Committed to the brand, repeatedly choose it, recommend it.
- Passive Loyalty: Choosing the brand out of convenience or habit; open to switching if persuaded.
Empowered Consumers and Marketing Shifts
- Consumer-driven marketing is replacing marketer-driven marketing.
- Two-thirds of active-evaluation touchpoints are driven by consumers.
- Consumer-driven channels (e.g., reviews, word-of-mouth, past experiences) influence active evaluation.
Integrated Marketing Communications (IMC)
- Top-Down Optimization Model: Evaluates overall communication integration, balancing short-term sales with long-term brand equity.
- Bottom-Up Matching Model: Matches media to consumer needs throughout the decision journey's stages.
- IMC Key Considerations: Consistency, complementarity, cross-effects (interactions among media)
Integration of Online & Offline Channels
- AR (Augmented Reality) merges online and offline experiences, providing a practical framework with applications from virtual mirrors to furniture arrangement apps.
Challenges in IMC
- Shifting consumer behavior and media usage patterns complicate communication integration.
- Digital media necessitate synchronized messaging across channels (e.g., social media, online ads.)
Theory (Situated Cognition, Embedded, Embodied, Extended Experiences)
- Situated Cognition Framework: AR-enabled customer experiences are conceptualized around three principles:
- Embedded Experiences: Integrate products/services into the consumer's immediate context. Virtual try-ons.
- Embodied Experiences: Simulate physical interactions, improve product evaluation through sensory engagement.
- Extended Experiences: Enable social sharing and collaborative decision-making.
