英英释义

Chi-squared test

  • abstract: Preface: The Chi-Square distribution is the distribution of the sum of the squares of a set of normally distributed random variables. Its value stems from the fact that the sum of random variables from any distribution can be closely approximated by a normal distribution as the sum as samples size increases.

双语例句

  • Care must be taken in the interpretation of the chi-squared test, since it has low power in the (common) situation of a meta-analysis when trials have small sample size or are few in number.

    必须重视对卡方分析结果的解释，因为当试验只有很小的样本量或者数量极小时，通常情况下Meta分析具有较低的把握度。
