Sampling Distribution Applet
Below is the applet that demonstrates the sampling distribution of sample means, which should open with the Wolfram CDF player (free to install for students!).
If you would rather not install the CDF player, you can try to SageMath verison that does not require you to install anything.
If using Chrome, download and open separately by clicking here.
This applet takes m samples of n uniformly distributed random integers between 0 and 9.
The output is a histogram of the sample means, and the mean of the sampling distribution (which approximates the mean of the population).
Try playing around with the sliders -- what happens to our results as we increase both numbers?
This applet was made by Andrew Sanchez for use at Tufts University.
