摘要
抽样误差和中心极限定理是卫生统计学教学中的重点和难点,纯理论讲授学生理解较为困难。利用Excel、SPSS、SAS等软件虽然可以进行随机抽样模拟试验,但编程语言较为复杂。R语言能够生动形象地展现从不同总体中进行随机抽样样本均数的分布规律,有助于学生理解均数抽样分布规律,提高教学效果。R语言具有丰富的统计函数和强大的绘图功能等优点,在卫生统计学各类常用统计量抽样分布教学中有重要应用价值。
Sampling error and central- limit theorem are the ~t and difficult points in Health Statistics teaching, and it is difficult for students to understand by spoon- feed teaching. Though random sampling simulation tests can be developed by Ex- cel, SPSS, SAS, the progrmmlting language is relatively complex. The R programming language can vividly shows saaaple mean distribution pattern from different population at the same time, which can help stimulate students＇ interests in leaning and improve classroom teaching effects. The R progranming language provides a wealth of statistic functions and powerful drawing functions, which has important application value in the teaching process of different commonly used statistics sampling dislribution of health statistics.
