›› Geogebra ›› The distribution of sample means
Click on the button "5 samples" to choose 5 separate samples from the population, calculate their means and plot their means. Click on the button "20 samples" to choose 20 separate samples from the population, calculate their means and plot their means. Each time either of these actions are carried out, two differently-sized samples will be used. You can change the size of these samples by entering the appropriate numbers in the input boxes. Do you notice any similarities between the population distribution and the distribution of the sample means? Do you notice anything differences between the population distribution and the distribution of the sample means? Can you explain why these similarities and differences exist?
