95prosent

95prosent is a term used to indicate the value of ninety-five percent, a common proportion in statistics, quality control, and everyday language. It denotes the fraction 95 out of 100 and is typically written as 95% or the decimal 0.95.

In practice, 95prosent is used to describe shares in a population, success rates in processes, or thresholds in decision rules. For example, if a survey reports that 95prosent of respondents support a policy, it means that 95 of every 100 respondents expressed support. It is important to distinguish between a observed proportion and related concepts such as probability or confidence levels, since sampling error can cause observed proportions to differ from the true population proportion.

Interpreting 95prosent requires context. A 95% level of precision or confidence is a separate concept: a confidence interval stated at 95% means that, if the same sampling procedure were repeated, about 95% of constructed intervals would contain the true value.

Etymology and usage: prosent originates from Latin pro centum via French pour cent and English percent. In Norwegian, Swedish and other languages, the term is used to express a portion of a whole in percentage terms.
