Table for Ascertaining Whether Differences between Percentages are Statistically Significant

A Framework for Finding Statistically Significant Differences

In the questionnaire analysis, finding whether there is a statistically significant difference between two or more groups in a continuous measure is one of the major problems in researches. However, it is difficult for researchers to solve the issue of finding possible statistically significant difference, namely “Statistically Significant Difference Unawareness Issue”. There are two causes to ...

DBit: Assessing Statistically Significant Differences in CDN Performance

As the volume of content served by content distribution networks (CDNs) grows, these networks evolve to improve performance. Their performance is difficult to characterize because it depends on a number of factors. In this paper, we develop a methodology called DBit that can determine whether one CDN’s user-perceived performance is statistically different from another. We validate DBit and demo...

Statistically significant sites

Most of us know less about statistics than we feel we should but, even as a scientist, it’s often not necessary to be an expert. When it comes to presenting your data, or reviewing someone else’s, however, it can help to have a ready reference at your fingertips. Before you run out and buy a textbook or ask advice from a colleague, take a look at what the web has to offer. Sites offering online...

Statistically Significant Results

Fortunately, the probability that the process was simply a chance encounter can be calculated, and a minimum threshold of statistical significance can be set. If the results are obtained such that the probability that they are simply a chance process is less than this threshold of significance, then we can say the results have a high probability of not being due to chance. Note that the probabi...
