Unbiased - The expectation of the observed values of various samples equals the corresponding population parameter. Let’s take, for example, We can say that sample mean is an unbiased estimator for the population mean. WebFeb 5, 2024 · An unbiased estimator for a population's variance is: s 2 = 1 n − 1 ∑ i = 1 n ( X i − X ¯) 2. where. X ¯ = 1 n ∑ j = 1 n X j. Now, it is widely known that this sample variance estimator is simply consistent (convergence in probability). I wonder, is it also true that it is strongly consistent, i.e. it converges to population variance ... dahua technology academy WebAnswer: Define “consistency”. Do you mean, “How can I tell if a set of sample data actually gives me a valid mean?” then what you do is compute the variance. The square root of the variance is the standard deviation.
