demonstrations in this chapter. Mean The mean of the sampling distribution of the mean sampling distribution formula is the mean of the population from which the scores were sampled. Therefore, if a population has a mean μ, then the types of sampling distributions mean of the sampling distribution of the mean is also μ. The symbol μM is used to refer to the mean of the sampling distribution of the mean. Therefore, the formula for the mean of the

## Sampling Distribution Definition

sampling distribution of the mean can be written as: μM = μ Variance The variance of the sampling distribution of the mean is computed as follows: That is, the variance of the sampling distribution of the mean is the population variance divided by N, the sample size (the number of scores used to compute a mean). Thus, the larger the sample size, the smaller the variance of the sampling distribution of the mean.

## The Standard Error Of The Mean

(optional) This expression can be derived very easily from the variance sum law. Let's begin by computing the variance of the sampling distribution of the sum of three numbers sampled from a population with variance σ2. The variance of the sum would be σ2 + σ2 + σ2. For N numbers, the variance would be Nσ2. Since the mean is 1/N times the sum, the variance of the sampling distribution of the mean would be 1/N2 times the variance of the sum, which equals σ2/N. The standard error of the mean is the standard deviation of the sampling distribution of the mean. It is therefore the square root of the variance of the sampling distribution of the mean and can be written as: The standard error is represented by a σ because it is a standard deviation. The subscript (M) indicates that the standard error in question is the standard error of the mean. Central Limit Theorem The central limit theorem states that: Given a population with a finite mean μ and a finite non-zero variance σ2, the sampling distribution of the mean approaches a normal distribution with a mean of μ and a variance of σ2/N as N, the sample size, increases. The expressions for the mean and variance of the sampling distribution of the mean

populations. Populations are just that - everyone in a specific group that we want to study. All Americans, NBA basketball players, churches, elderly Swedes, injection drug users in Seattle, sampling distribution questions and answers Duke undergraduates, etc. In general, it is prohibitively expensive or time-consuming

## Sampling Distribution Examples With Solutions

to conduct a survey of an entire population. So, we choose a group of people from our population sampling distribution khan academy to study. Because we only choose a small group, our data will contain some errors (we call them sampling errors). That is, if we wanted to know average NBA http://onlinestatbook.com/2/sampling_distributions/samp_dist_mean.html salary, and chose 20 NBA players out of all NBA players and asked their salaries, we'd get a slightly different answer if we repeated this process several times. The amount of error that this process induces is called sampling error. It's especially important to consider with very small samples. When we repeatedly sample from a population, and record https://rstudio-pubs-static.s3.amazonaws.com/22197_5ecd34c6881d458c94fd207bd0634797.html our means, we end up with a sampling distribution. We want to quantify how close a statistic from a sample is likely to be from the true population parameter. To do this, we calculate standard errors. Standard errors take advantage of the Central Limit Theorem that states that, if we take a bunch of samples from a population and calculate the mean of those samples, those sampled means will be normally distributed around the true population mean. Therefore: If we take a bunch of samples and calculate their means (the sample means), and then calculate the mean of the sample means, that will be the population mean. And: If we take a bunch of samples and calculate their sampling means, and then calculate the standard deviation of those sampling means from the population mean (or the mean of the sampling means) that is the standard error. ** You will need to review the material in chapters 5-7 of Urdan for this Homework. ** ** Also: you will need to execute the fo
