This report presents a Chi-Square Goodness-of-Fit Test for Research Scenario 1 (Assignment 4). The analysis examines whether dessert preferences (chocolate cake, vanilla cheesecake, tiramisu) among 548 participants differ from an equal distribution. Results indicate a statistically significant difference, with chocolate cake being the most preferred option. Effect size (Cohen’s W = 0.31) suggests a moderate deviation from equal preference.
