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 ...

Just because a result has statistical significance, it doesn't mean that the result has any real-world importance. To help 'translate' the result to the real world, we can use an effect size. An effect size is a numerical index of how much your dependent variable of interest is affected...
Researchers use a measurement known as thep-value, or probability value, to determine statistical significance. If the p-value falls below the significance level, the result is statistically significant. The p-value is a function of the means and standard deviations of the data samples. It indica...
That means your results must have a 5% or lower chance of occurring under the null hypothesis to be considered statistically significant. The significance level can be lowered for a more conservative test. That means an effect has to be larger to be considered statistically significant. The ...
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...
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...
We will help you through the complex world of statistics as we explore how to determine statistical significance and what it means when something is statistically significant. Statistical significance The claim that a set of observed data are not the result of change but can instead be attributed ...
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...
