In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate...

size determination or estimation is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is...

The indentation size effect (ISE) is the observation that hardness tends to increase as the indent size decreases at small scales. When an indent (any...

-value for this result is 0.6113 {\displaystyle 0.6113} To compute an effect size for the signed-rank test, one can use the rank-biserial correlation....
