Ch 7. 7) A sampling distribution shows every possible result a statistic can take in every possible sample from a population and how often each result happens - and can help us use samples to make predictions The distribution of possible values of a statistic for repeated samples of the same size is called the sampling distribution of the statistic. 4 Answers will vary. Repeat the work you did in the previous worksheet by using now samples of n = 3 23 or higher? b) Describe the sampling distribution of mean ACT scores for samples of 50 students. (center, spread, shape) 4) What is the shape of the sampling distribution above? 5) What would the shape of the sampling distribution be if the The mean of the sampling distribution is the same as the mean of the population: μ = μ x The standard deviation of the sampling distribution gets smaller according to σ this equation: σ = x n The Central The sampling distribution of a statistic is the distribution of all possible values taken by the statistic when all possible samples of a fixed size n are taken from the population. Sampling Distributions & Confidence Intervals: Proportion. . c) a. This document Knowing the sampling distribution of the sample mean will not only allow us to find probabilities, but it is the underlying concept that allows us to estimate the population mean and draw conclusions about While the sampling distribution for sample means and sample proportions is roughly bell shaped, other sampling distributions can take on di erent shapes, e. a.
