T T07-01 Sample Size Effect – Normal Distribution Purpose Allows the analyst to analyze the effect that sample size has on a sampling distribution. A graphical display showing the approximate normal sampling distribution is created. Inputs Mean Scenario Population Mean & Standard Deviation Sample Size 1Sample Size 2 Outputs Sampling Distribution Statistics Mean & Standard Error for both sampling distributions Graph of Sampling Distribution for both sampling distributions

T Mean Scenario: Example Calculate the sampling distribution mean and standard error for a sample of size 30 and a sample of size 100 drawn from a population with the following parameters population mean of 51,800 population standard deviation of 4000 Draw a graph comparing the two sampling distributions.

T Mean Scenario: Input the mean, standard deviation Input sample size for Sample 1 and Sample 2.

T Sampling Distribution statistics and graph are automatically calculated
