sampling distribution

probability distribution of a sample statistic


relationships between population mean and mean of the sampling distribution of the sample mean

equal no matter what sample size


relationship between population variance and variance of the sampling distribution of the sample mean

variance of sampling distribution of the sample mean = population variance / n


relationship between population mean and mean of the sampling distribution of the sample mean

equal no matter what sample size


relationship between population standard deviation and standard deviation of the sampling distribution of the sample mean

standard deviation of the sampling distribution of the sample mean = population standard deviation / square root(n)


variance / standard deviation of the sampling distribution of the sample mean ________ as the sample size increases. and why?

decreases
values of sample mean for are getting closer to population mean as size increases 

standard error

standard deviation of the sampling distribution of a sample statistic


standard error of the sample mean

standard deviation of the sampling distribution of the sample mean


standard error of the sample variance

standard deviation of the sampling distribution of the sample variance


sampling distribution of a sample statistic depends on what 3 things

sample statistic of interest
population sample size 

if the population is normal, then the sampling distribution of the sample mean is...

normal


standard score

(value  mean)/standard deviation


central limit theorem

for any population distribution, for a large sample sample size (at least 30), the sampling distribution of the sample mean is normal
