Statistical inference. Not to be confused with Statistical interference. Statistical inference is the process of deducing properties of an underlying distribution by analysis of data. Inferential statistical analysis infers properties about a population: this includes testing hypotheses and deriving estimates.
The Presbyterian Church (USA) , or PC(USA) , is a mainline Protestant Christian denomination in the United States.
Its name is often confused with the Presbyterian Church in America [a.k.a. PCA]. The PCA is a smaller and much more conservative denomination. It split from the PCUSA decades ago because it could not accept the concept of female clergy. The PCA's beliefs and practices concerning lesbian, gay and bisexual ordination are discussed in a separate essay.
