The Power of Replicated Measures to Increase Statistical Power
Advances in Methods and Practices in Psychological Science, 2019When running statistical tests, researchers can commit a Type II error, that is, fail to reject the null hypothesis when it is false. To diminish the probability of committing a Type II error (β), statistical power must be augmented.

In this chapter, we focus on approximation problems motivated by studies on the asymptotic behavior of power-divergence family of statistics. These statistics are the goodness-of-fit test statistics and include, in particular, the Pearson chi-squared statistic, the Freeman–Tukey statistic, and the log-likelihood ratio statistic.

The Importance of Statistical Power Calculations
Headache, 2018When planning research, collecting data, or interpreting an analysis, a crucial research design consideration is the size of the study sample. Typically, all of the individuals in a certain population of interest cannot be evaluated, so a researcher must

Pediatrics, 1987
To the Editor.— Dr Donowitz described an interesting research project in which the efficacy of overgown use in the prevention of pediatric intensive care unit nosocomial infection was examined.1 He concludes that "overgowns were an expensive and ineffective method of preventing or decreasing nosocomial infections."1 Although Dr Donowitz ...
