[58] SB 966: Pharmacy benefits
Pharmacy benefits managers (PBMs) are employing new strategies to squeeze independent pharmacies, even as the industry faces pressure from the federal government, which is looking for ways to curb ...
Insensitivity to sample size is a cognitive bias that occurs when people judge the probability of obtaining a sample statistic without respect to the sample size.For example, in one study, subjects assigned the same probability to the likelihood of obtaining a mean height of above six feet [183 cm] in samples of 10, 100, and 1,000 men.
A bubble chart is a type of chart that displays three dimensions of data. Each entity with its triplet (v 1, v 2, v 3) of associated data is plotted as a disk that expresses two of the v i values through the disk's xy location and the third through its size. Bubble charts can facilitate the understanding of social, economical, medical, and ...
The figure shows the change in p-values computed from a t-test as the sample size increases, and how early stopping can allow for p-hacking. Data is drawn from two identical normal distributions, N ( 0 , 10 ) {\displaystyle N(0,10)} .
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 of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...
Matched or independent study designs may be used. Power, sample size, and the detectable alternative hypothesis are interrelated. The user specifies any two of these three quantities and the program derives the third. A description of each calculation, written in English, is generated and may be copied into the user's documents.

That is, a misuse of statistics occurs when a statistical argument asserts a falsehood. In some cases, the misuse may be accidental. In others, it is purposeful and for the gain of the perpetrator.
