What caused the lack of statistically significant reduction in the overweight and obese group?A. They were told not to eat a lot.B. In the study they had no appetite to eat.C. They lost consciousness in the study.D. They ate less food on purpose. 相关知识点: ...
On the surface, Version B seems to be performing better with more leads. But to be confident that this difference is not just due to chance, you conduct a statistical test and find that the results are statistically significant. This tells you that the difference in performance between the tw...
Statistical probability minimises this from happening.1 Statistical probability or p values reveal whether the findings in a research study are statistically significant, meaning that the findings are unlikely to have occurred by chance. To understand the p value 鈥...
An FDR adjusted p-value (or q-value) of 0.05 implies that 5% of significant tests will result in false positives. The latter will result in fewer false positives.q-valuesQ-values are the name given to the adjusted p-values found using an optimised FDR approach. The FDR approach is ...
the U.S. Census Bureau stipulates that any analysis with a p-value greater than 0.10 must be accompanied by a statement that the difference is not statistically different from zero. The Census Bureau also has standards in place stipulating which p-values are acceptable for various publications.1...
T values, P values, and poker hands T values of larger magnitudes (either negative or positive) are less likely. The far left and right "tails" of the distribution curve represent instances of obtaining extreme values of t, far from 0. For example, the shaded region represents the probabili...
A third approach is to apply the FDR correction which estimates the number of false positives for a given confidence level and adjusts the critical p-value accordingly. For this method statistically significant p-values are ranked from smallest (strongest) to largest (weakest), ...

Statistical significance is a result of hypothesis testing that arrives at a p-value or likelihood that two or more variables are caused by something other than chance. A 5% p-value tends to be the dividing line. The lower the value, the more statistically significant the result of the data...
