A picture of the apparatus for an experiment about bell curves.
In this section we run a car down a track 100 times to measure the spread in the car’s run times. We plot these run times in a “Histogram” plot. We give instructions on how to perform a simple experiment at home to introduce the concept of a normal distribution (or a “Bell Curve”), a key concept in a branch of mathematics called “Statistics.” We also introduce the use of decimal notation in expressing a car’s run time.
Introducing the Gaussian or Normal distribution (also known as a bell curve).
Introducing the concept of decimal notation by relating to counting money.
Introducing a histogram as a way to visualize many test runs of a car.
