Thepvalueis a number, calculated from a statistical test, that describes how likely you are to have found a particular set of observations if the null hypothesis were true. Pvalues are used inhypothesis testingt

Researchers typically use p-values as evidence when testing a hypothesis. A p-value is a statistical measurement to discover how likely an observed outcome is the result of chance. Smaller p-values usually mean there's likely to be a stronger relationship between two variables, thus rejecting ...
Opponents of the efficient markets hypothesis advance the simple fact that there ARE traders and investors – people such as John Templeton, Peter Lynch, and Paul Tudor Jones – who DO consistently, year in and year out, generate returns on investment that dwarf the performance of the ove...

All genes with p-values ≤3.81e-03are considered significant. The expected rate of false discoveries among these significant genes is at most 5%. Remember that this interpretation is in the context of the entire set of hypothesis tests. Each individual gene with a p-value ≤2e-05doesn’t ha...
While this post looks at significance levels from a conceptual standpoint, learn about thesignificance level and p-valuesusing a graphical representation of how hypothesis tests work. Additionally, my post about thetypes of errors in hypothesis testingtakes a deeper look at both Type 1 and Type II...
This is a two-sided test for the null hypothesis that two independent samples have identical average (expected) values. This test assumes that the populations have identical variances by default.We can use this test, if we observe two independent samples from the same or different population. ...
P values <.05 were considered statistically significant. SAS V9.4 (SAS Institute) was used for the analysis. Results In this cross-sectional study, 215 volunteers completed the survey (116 written, 99 verbal). Respondents had a mean (SD) age of 42 (17) years, 140 (65%) had a ...
s values, beliefs, social standing, and degree of shared interests (McPherson et al.,2001). In a social network, community receptivity is what makes people feel like their individual traits fit in the group (Ruyter & Conroy,2002). It’s harder to build receptivity in online communities than...
