教育实验中关于平均数的统计分析

Static Analysis of Average Value in Education Experiment

结合实例，介绍了教育实验中总体服从正态分布（方差已知或未知，大、小样本）或总体非正态几种情形下样本平均数与总体平均数间差异显著性的检验方法；介绍了两组样本独立或相关条件下，两总体平均数间差异显著性检验方法，以及平均数间多重比较的t检验法和q检验法。

Based on examples, introduces significance of difference test method between sample average and ensemble average in cases of totality submission normal distribution(variance known of unknown big, small sample) or totality non - normal distribution in education experiment; presents two ensemble averages’singnificance of difference test method in conditions of two groups sample independence or dependence and introduces t and q test of average multiple comparison
