epävarmuusvälin
An epävarmuusväli, or confidence interval in English, is a statistical concept used to express the uncertainty associated with a sample statistic. It provides a range of values within which the true population parameter is likely to lie, with a certain level of confidence. For example, a 95% confidence interval means that if we were to repeat the sampling process many times, 95% of the calculated intervals would contain the true population parameter.
The width of an epävarmuusväli is influenced by several factors. A larger sample size generally leads to
Epävarmuusvälit are crucial for interpreting research findings. They allow researchers and consumers of research to understand
