In statistics, statistical significance means that the result that was produced has a reason behind it, it was not produced randomly, or by chance.SciPy provides us with a module called scipy.stats, which has functions for performing statistical significance tests. ...
Statistical significance means that the numbers are reliably different, greatly aiding your data analysis. Still, you should also consider whether the results are important — it's up to you to decide how to interpret or take action on your results. For example, say you receive more customer ...
[统计] 统计显著性；统计数据 However, the study included only 71 men, which means that the findings didn’treach statistical significance.但是，研究只针对了71名男性，这意味着这个研究结果并没有达到统计显著性
statistical significance A term used in statistical analysis when a hypothesis is rejected. As a general rule, the non plus minimum significance level is 5%—i.e., it is said to be significant at the 5% level—which means that when the null hypothesis is true, there is only a 1-in-20...

Researchers use a measurement known as thep-valueto determine statistical significance; if the p-value falls below the significance level, then the result is statistically significant. The p-value is a function of the means and standard deviations of the data samples. ...
statistical significance Definitions(1) Word of the Day Advertisement Instatistics, a number that expresses the probability that the result of a given experiment or study could have occurred purely by chance. This number can be a margin of error (“The results of this public opinion poll are ac...
Practical Significance Statistical Significance Significant differences (i.e., reject the null hypothesis) means that differences in group means are not likely due to sampling error. The problem is that statistically significant differences can be found even with very small differences if the sample ...
that statistical significance tells them that the results must have meaningful real-world implications, that the results are practically significant. But, unfortunately, that’s not what it means either. The term significant is qualified with the term statistically. It doesn’t mean generally significa...
