mean=平均值 proportion=比例 sampling distribution of the sample mean 样本均值抽样分布 样本均值的抽样分布即所有样本均值的可能取值形成的概率分布。例如，某高校大一年级参加英语四级考试的人数为6000人，为了研究这6000人的平均考分，欲从中随机抽取500人组成样本进行观察。若逐一抽取全部可能样本，并计算...

Introduction to Sampling Distributions, Variance Sum Law ILearning Objectives State the mean and variance of the sampling distribution of the mean Compute the standard error of the mean State the central limit theoremThe sampling distribution of the mean was defined in the section introducing sampling...
The Sampling Distribution of the Mean is the mean of the population from where the items are sampled. If the population distribution is normal, then the sampling distribution of the mean is likely to be normal for the samples of all sizes.
This lesson covers sampling distribution of the mean. Explains how to compute standard error. Includes problem with step-by-step solution.
Experienced Tutor Specializing in DAT, Pharmacology and Calculations About this tutor › The mean of the sampling distribution is the same as the probability of correctly identifying a Skittle's color, which is 17%. So, the mean here is 0.17. To find the standard deviati...
