The principal goal of the annual Music Information Re-trieval Evaluation eXchange (MIREX) experiments is to determine which systems perform well and which systems perform poorly on a range of MIR tasks. However, there has been no systematic analysis regarding how well these evaluation results transl...

Anyone with previous experience of WordPress split testing tools will be able to appreciate the simplicity of Divi Leads, which is due in part to its seamless integration into theDivi Builder. With it, you’ll be able to both run and check on the results of your tests without eve...
This brings us to a key point: statistical significance tells us that a difference or relationship exists, but it doesn’t tell us how big or important that difference is. For example, if you had only asked 50 customers instead of 500, that 20-vote difference might not have shown up as...
What does it tell us? At first, many people think that a statistically significant result using a 95% confidence interval tells them that there is a 95% chance they’re correct and a 5% chance they’re incorrect. But, unfortunately, that’s not what it means. Its meaning is much more ...
For example, if it is statistically significant you would then look at the direction of the sample means to see whether for example the group that received the exercise group improved more over time than the control group. This can be contrasted with the two main effect...
The overall test, if statistically significant, simply shows that there issomeassociation other than “chance” in the table. But it does not tell youwhatthe association is. Many times, it is fairly obviouswhatthe association is because there are clear patterns in the data. In those cases, ...
significance argument when authors try to wiggle out of a statistically non-significant result that runs counter to their clinically hypothesized (or desired) result. If one is willing to argue that P values of 0.25 and 0.17 are reliable enough to draw scientific conclusions, why ...
Suppose Alex, a financial analyst, is curious as to whether some investors had advance knowledge of a company's sudden failure. Alex decides to compare the average ofdaily market returnsbefore the company's failure with those after to see if there's a statistically significant difference between ...
How Can You Use P-Value to Compare Two Different Results of a Hypothesis Test? If you have two different results, one with a p-value of 0.04 and one with a p-value of 0.06, the result with a p-value of 0.04 will be considered more statistically significant than the p-value of 0.06...
