Webb24.4 - Mean and Variance of Sample Mean. We'll finally accomplish what we set out to do in this lesson, namely to determine the theoretical mean and variance of the continuous random variable X ¯. In doing so, we'll discover the major implications of the theorem that we learned on the previous page. Let X 1, X 2, …, X n be a random sample of ... WebbField potential (FP) recording is an accessible means to capture the shifts in the activity of neuron populations. However, the spatial and composite nature of these signals has largely been ignored, at least until it became technically possible to separate activities from co-activated sources in different structures or those that overlap in a volume.
