The p-values are a decimals between 0 and 1 that represent the probability that the data given to us occurred by chance under the hypothesis test. Simply put, the lower the p-value, the better the chance that we can reject the null hypothesis. For our purposes, ...
Public health situations faced by family physicians and other primary care practitioners, such as severe acute respiratory syndrome (SARS) and more recently H1N1, have resulted in an increased interest to identify the public health competencies relevant to family medicine. At present there is no ...

First, P value calculations assume that the null hypothesis is correct. Thus, from the P value’s point of view, the null hypothesis is 100% true. Remember, P values assume that the null is true, and sampling error caused the observed sample effect. Second, P values tell you how consist...
What is the P-Value ?The P-Value is a statistical representation of the likelihood that the null hypothesis is true. Therefore the P-Value is the probability that the output (Y) will not change as a result of the variation that we are deliberately introducing in the input (X)....
P-Value The P-value is a probabilistic measure indicating the likelihood that an observed value occurred by random chance. It assesses the significance of differences observed in the dependent variable when the corresponding independent variable changes. A lower P-value signifie...
A statistically significant test also does not imply that the observed difference is clinically important or meaningful, and their meanings are often confused. 展开 关键词: clinical significance confidence interval equivalence test p-value DOI: 10.4066/amj.2009.191 被引量: 1 ...
This page shows the t test for each row. The P value for each comparison is shown, along with themultiplicity adjusted P value, which is higher. Additionally, columns for transformations of the P value are included if selected on theOptions tabof the parameters dialog. These transformations in...
very small datasets the Q values produced can be smaller than the initial p-values - particularly if many of the p-values are small. This seems wrong. As Q values are interpreted as p-values adjusted for the false discovery rate, shouldn't they always be larger than the initial p-va...
