Introduction
This report is based on a primary survey conducted to analyze customer satisfaction and preferences among Food items like Pizza, Burger, Noodles and Shevpuri. Data was collected from 25 respondents using a structured Google Form questionnaire. The responses were recorded on a rating scale of 1 to 10, reflecting varying levels of customer satisfaction. This research aims to evaluate and compare customer perceptions, service quality, and overall experience across the stalls. The findings help in identifying customer preferences and key factors influencing their choices. Overall, the study provides insights into the competitive positioning of food items in the market.
Objective
To compare 4 Food Items by way of One-Way ANOVA.
Literature Review
Moreover, Nestle Marion (2013) emphasized that food marketing and advertising strongly influence consumer choices, especially among children and teenagers, affecting their preference for specific food items.
Similarly, Brian Wansink (2004) found that environmental factors such as portion size, packaging, and presentation significantly affect how people select and consume food items. His research shows that people often eat more due to external cues rather than hunger.
