摘要
为了了解某大学周边水果市场及消费者对水果的需求,本文采用问卷调查方法对某大学的学生和周边市民进行随机抽样调查。运用了列联表分析、多重响应、独立样本t检验、多个独立样本非参数检验法对样本进行统计分析。得出某大学学生和周边市民喜欢吃水果的程度有显著差异,消费者是否是学生与消费者购买水果的地方以及每次购买水果的费用之间具有显著的相关性,消费者购买水果的频率与购买地之间具有显著的相关性。
In order to understand the fruit market around a university and consumers’ demand for fruit, a questionnaire survey was conducted to randomly sample the students and citizens of a university. Statistical analysis of samples was performed using contingency table analysis, multiple responses, independent sample t test, and multiple independent sample nonparametric test methods. The results showed that there was a significant difference in the degree of fruit consumption between the students of a university and the citizens nearby. There was a significant correlation between whether the consumer was the place where the consumer bought the fruit and the cost of each purchase. There was a significant correlation between how often consumers bought fruit and where they bought fruit.
