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
