Standard error of the mean decreases
as sample size increases
standard error of the mean value is influenced by the
standard deviation of the population
Standard error of the mean...
measures the variability in the sample means
the probability distribution of all possible values of the sample means called the
sampling distribution of the sample mean
The value of the sample statistic is used to estimate
the value of the population parameter
The standard deviation of a point estimate is
the standard error
The standard deviation of x̄ is referred to as
the standard error of the mean
The finite correction factor should be used in the computation σ x̄ and σȳ when n/N is
greater than .05
The standard deviation of p̄ is referred to as
the standard error of the population
a numerical measure from a population such as a population mean is called a
parameter
