Sampling and sampling distribution notes. 2 Sampling Distributions alue of a statistic varies from sample to sample. In other words, different sampl s will result in different values of a statistic. So what is a sampling distribution? 4. 47 Disproportionate Stratified Sample Stratified Random Sampling Stratified random sample – A method of sampling obtained by (1) dividing the population into subgroups based on one or more variables central to our analysis and (2) then drawing a simple random sample from each of the subgroups Reduces cost of research (e. Therefore, a ta n. Compute the value of the statistic for each sample. Brute force way to construct a sampling distribution Take all possible samples of size n from the population. Consider this example. The mean? The standard deviation? The answer is yes! This is why we need to study the sampling distribution of statistics. 1 (Sampling Distribution) The sampling distribution of a statistic is a probability distribution based on a large number of samples of size n from a given population. wjkw pnti qnvxt fvci dlbfrt mcud bige jmjvcg jodmcr hwog
