Define the term standard error. Why is the standard error important in research using sample distributions?
Consider the following scenario: A random sample obtained from a population has a mean of µ=100 and a standard deviation of σ = 20.
The error between the sample mean and the population mean for a sample of n = 16 is 4 points and the error between a sample men and population mean for a sample of n = 100 is 2 points.
Explain the difference in the standard error for the two samples.
