significance level
词性:名词
中文翻译:显著性水平,显著水平
英文释义:
The significance level is a statistical concept used in hypothesis testing to determine if there is enough evidence to reject the null hypothesis. It represents the probability of rejecting the null hypothesis when it is actually true.
显著性水平是在假设检验中使用的一个统计概念,用于确定是否有足够的证据来拒绝原假设。它代表了当原假设实际上为真时,拒绝原假设的概率。
例句:
- The significance level for this hypothesis test was set at 0.05. (这个假设检验的显著性水平设定为0.05。)
- Researchers often choose a significance level of 0.01 for more stringent testing. (研究人员经常选择0.01的显著性水平进行更严格的检验。)
- It is important to set an appropriate significance level to avoid making incorrect conclusions. (设置适当的显著性水平是避免得出错误结论的重要因素。)
词性:形容词
中文翻译:显著性的,重要性的
英文释义:
As an adjective, significance level refers to the level of importance or significance of something.
作为形容词时,significance level 指的是某事物的重要性或显著性水平。
例句:
- The findings of the study have significant implications for future research. (这项研究的发现对未来的研究具有重要意义。)
- There was a significant difference in performance between the two groups. (这两组之间的表现存在显著差异。)
- The results of the experiment were not statistically significant. (实验结果在统计上不具有显著性。)
词语辨析:
1. significance level vs. confidence level:
显著性水平和置信水平是统计学中两个不同的概念。显著性水平用于假设检验,代表拒绝原假设的概率;而置信水平用于估计,代表估计结果落在一个置信区间内的概率。
词汇扩充:
1. statistical significance: 统计显著性
2. level of significance: 显著性水平
3. null hypothesis: 原假设
4. alternative hypothesis: 备择假设
5. p-value: p值
6. reject the null hypothesis: 拒绝原假设
7. accept the null hypothesis: 接受原假设
近义词:
1. level of confidence
2. level of importance
3. level of significance

柯林斯词典(Collins Dictionary):
significance level (noun)
The significance level of a result from a statistical test is a way of showing how reliable the result is, or how likely it is that the result could have happened by chance.
牛津词典(Oxford Dictionary):
significance level (noun)
A level of significance is a value below which results are regarded as statistically significant.
用法:
The significance level is commonly set at 0.05, meaning that if the p-value is less than 0.05, the result is considered statistically significant and the null hypothesis is rejected.
显著性水平通常设定为0.05,这意味着如果p值小于0.05,则结果被认为是统计显著的,原假设被拒绝。
