Decoding Consumer Cravings
A data-driven exploration of the snack industry. This project analyzes survey data to uncover the hidden drivers behind teenagers' potato chip purchasing decisions and brand loyalty.
The Context
Understanding consumer preferences is the foundation of effective product strategy. In a highly saturated snack market, brands must know exactly what drives a customer to pick up one specific bag over another.
The goal of this project (completed in Aug. 2022) was to analyze primary survey data targeting the 15 to 18 age demographic. The objective was to answer fundamental market research questions and translate raw responses into actionable insights.
Core Research Questions
- The Purchase Driver: What dictates choice the most (flavor, price, or brand)?
- Consumption Habits: When and where do consumers eat snacks, and what package size do they prefer?
- Health Consciousness: Do consumers actively check calorie counts when buying traditionally indulgent snacks?
Survey Design & Data Collection
To evaluate preferences accurately, a targeted consumer survey was deployed. Gathering both quantitative and qualitative data was essential to building a comprehensive demographic profile.
Data Gathering
Deployed a structured questionnaire using Voluntary-Response Sampling. The process targeted teenagers and successfully captured 37 valid responses.
Variables Examined
Tracked key consumer attributes including flavor preferences, spending habits, packaging design (foil versus cylinder), and point of purchase.
Data Preparation
Cleaned the raw survey responses (filtering out incomplete or invalid text entries) to prepare the dataset for exploratory analysis.
Key Findings
The analysis revealed several distinct patterns in how teenagers evaluate and purchase potato chips.
- Flavor is Supreme: 86.5% of respondents indicated flavor as the absolute primary driver for their choice, with BBQ (48.6%) and Original (43.2%) emerging as the top favorites.
- Brand Dominance & Packaging: Lay's captured a massive 83.8% of the preferred brand share. Additionally, over 70% of participants preferred traditional foil packaging over cylinder containers.
- Context & Health: Over half the respondents eat chips primarily while watching TV or Netflix, heavily favoring medium-sized (70g) bags. The data also showed that the majority do not actively consider calories (with a mode of 1 on a 5-point concern scale).
Methodology & Analytical Integrity
A strong analysis requires an honest evaluation of its own boundaries. Understanding the limitations of the data gathering process is critical for drawing responsible conclusions.
- Methodology Snapshot: Applied foundational statistical methods to summarize the data. This included calculating measures of central tendency (mean, median, mode), interquartile ranges (IQR), and generating Five Figure Summaries visualized through Box-and-Whisker plots.
- Addressing Bias: The voluntary-response sampling introduced specific limitations. The sample had a noticeable gender bias (predominantly male) and a national bias (majority Chinese participants), limiting the ability to generalize findings to a broad Western demographic.
- Response Constraints: The survey encountered minor response bias, where a few participants provided incomplete explanations or nonsensical text inputs. This reinforced the importance of manual data validation.
