Statistically Significant Results
ثبت نشده
چکیده
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 probability is never zero; statistical tests are never 100% certain. Threshold levels merely indicate the risk we are willing to take when it comes to accepting or rejecting a particular hypothesis.

متن کاملA randomized trial in a massive online open course shows people don’t know what a statistically significant relationship looks like, but they can learn
Scatterplots are the most common way for statisticians, scientists, and the public to visually detect relationships between measured variables. At the same time, and despite widely publicized controversy, P-values remain the most commonly used measure to statistically justify relationships identified between variables. Here we measure the ability to detect statistically significant relationship...

It's easy to read far too much into the word significant because the statistical use of the word has a meaning entirely distinct from its usual meaning. Just because a difference is statistically significant does not mean that it is important or interesting. A statistically significant result may not be scientifically significant or clinically significant. And a difference that is not significa...
متن کاملAlmost all articles on cancer prognostic markers report statistically significant results.
We aimed to understand the extent of the pursuit for statistically significant results in the prognostic literature of cancer. We evaluated 340 articles included in prognostic marker meta-analyses (Database 1) and 1575 articles on cancer prognostic markers published in 2005 (Database 2). For each article, we examined whether the abstract reported any statistically significant prognostic effect ...

Background: Beta thalassemia is one of the autosomal recessive diseases that related to synthesis disorder of beta globin chain. It is caused by any of the more than 200 mutations in the β-globin gene. DNA sequencing and genotyping of numerous mutations at beta globin gene is timely and expensive. Therefore, the best method for screening is linkage using polymorph markers at beta globin region ...
متن کاملReporting of statistically significant results at ClinicalTrials.gov for completed superiority randomized controlled trials
BACKGROUND Publication bias and other reporting bias have been well documented for journal articles, but no study has evaluated the nature of results posted at ClinicalTrials.gov. We aimed to assess how many randomized controlled trials (RCTs) with results posted at ClinicalTrials.gov report statistically significant results and whether the proportion of trials with significant results differs ...
