Usaldusastme
Usaldusastme, often translated as confidence interval, is a statistical concept used to estimate a population parameter. It provides a range of values, within which the true population parameter is likely to lie, with a certain level of confidence. This confidence level, typically expressed as a percentage (e.g., 95%), indicates the probability that if the same sampling procedure were repeated many times, the calculated confidence intervals would contain the true population parameter.
A confidence interval is constructed from sample data and is defined by two values: a lower limit
It is important to understand that a confidence interval does not state the probability that the true
