Parameter of interest statistics meaning
WebWhen using a sample statistic to estimate a population parameter, some statistics are good in the sense that they target the population parameter and are therefore likely to yield good results. Such statistics are called unbiased estimators. Sample mean, sample variance and sample proportion are the examples of unbiased estimators. WebIf you measure the entire population and calculate a value like a mean or average, we don’t refer to this as a statistic, we call it a parameter of the population. The Sampling …
