In the graph above, the two shaded areas are equidistant from the null hypothesis value and each area has a probability of 0.025, for a total of 0.05. In statistics, we call these shaded areas the critical region for a two-tailed test. If the population mean is 2...

which may be expressed as a findingof significanceStatistics A measure of deviation of data from a statistical mean, defined by a probability–p value, where a p of 0.05 indicates a 5% possibility or 1 chance in 20 that a dataset differs from a mean and 19 chances that it will not. See...

Next, we need to calculate the z-score which will allow us to get the p-value. The z-score is a normalized score that allows us to compare the probability of the U score occurring in our distribution. statistics.laerd.com/st The equation to get the z-score is: ...

There’s also a common trap where "significant" is used interchangeably with "important." While this might work in everyday conversation, in the realm of statistics, "significant" has a very specific meaning—it refers to the likelihood that a result is not due to random chance. That said,...
Statistical significance is a measure ofwhether your research findings are meaningful. More specifically, it’s whether your stat closely matches what value you would expect to find in an entirepopulation. As a simple example, let’s say you worked for a polling company and asked 120 people how...
formulation do not differentiate between the methods. Often a p value is calculated in order to test against α. Concepts such as specificity and sensitivity, requiring two hypotheses, are often mixed up with p values. Outside specialiststatistics, mostchemometricsexperts would not distinguish the ...
