Oftentimes, teachers struggle to explain the central liimt theorem (CTT) to students. This concept is at the heart of inference and should be made clear as early as possible.

Using the Central Limit Theorem App, students can see how the histogram of the sample means from any of the four provided distributions approach the "bell shape" curve as the number of samples is increased.

The same app also enables us to show the rate of convergence to the bell shape curve of the histogram of the sample means as we increase the sample size.

The figure below shows the interface of the app.

The app is available in this link: https://jtabadero.shinyapps.io/coursera_developing_data_products_final/

If you want to improve the app, you can head on to the github repository: https://github.com/josephuses/coursera_developing_data_products_final
