The Survey System uses significance levels with several statistics. In all cases, the p value tells you how likely something is to be not true. If a chi square test shows probability of .04, it means that there is a 96% (1-.04=.96) chance that the answers given by different groups...

Significance in statistics is an important term when it comes to interpreting the results of statistical tests. It enables one to conclude that a result is not merely due to chance. To identify whether the result of a test is statistically significant, we often compare the significant level ...

For example, consider the T and P in your t-test results. “Curiouser and curiouser!” you might exclaim, like Alice, as you gaze at your output. What are these values, really? Where do they come from? Even if you’ve used the p-value to interpret the statistical significance of your...

What information is needed to evaluate whether an effect obtained in an experiment is large enough to have "practical" or "clinical" significance? How should a researcher illustrate the findings in a research study? Why is it important to address your research questions in the conclusion of y...
In a nutshell, the greater the difference between two observed values, the less likely it is that the difference is due to simple random chance, and this is reflected by a lower p-value. What Is the Significance of a P-Value? The p-value approach to hypothesis testing uses the calculated...
In order to comprehend and interpret the data we gather, statistical analysis is a crucial tool. The significance of statistical analysis is best exemplified by the following points: Identify patterns and trends: Data that may not be obvious to the human eye can be analyzed statistically to revea...
In statistics, a p-value is used to indicate whether the findings are statistically significant. It is possible to determine that two variables are correlated, but there may not be enough supporting evidence to state this as a strong claim. A high p-value indicates there is enough evidence to...
