Over a period of 56 years, 12,686 appendectomies were done for acute appendicitis at the Jersey City Medical Center in Jersey City, New Jersey. We tabulated each appendectomy by the month and season of its occurrence. The spring and summer months had the highest incidence and the fall and winter the lowest. Using analysis of variance, however, we found no statistically significant variation in incidence.
在56年的时间里，新泽西州泽西城的泽西城医疗中心为急性阑尾炎进行了12686例阑尾切除术。我们按阑尾切除术发生的月份和季节将每例手术制成表格。春季和夏季的发病率最高，秋季和冬季最低。然而，通过方差分析，我们发现发病率没有统计学上的显著差异。
