A Chi-Square Goodness-of-Fit Test was conducted on the categorical variable Kinds of Dessert to determine if the observed distribution of preferences among the sample differed significantly from the equal expected proportions of 33.33% for each kind. With a sample size of 548, there was a statistically significant difference between the observed and expected proportions, p-value is 2.838e-13 and X-squared (df=2, N=548) is 57.781. This indicates that the preference for the different kinds of dessert is not equal in the population. The most preferred dessert was ChocoCake, while Tiramisu was the least preferred. The effect size, calculated as Cohen’s W was 0.32, which is considered a medium size effect.
