Relative Frequency Training

Greetings, future Head Chicken Checker!

As a scientist, you will often need to know how likely a certain event might occur. We call this likelihood a probability. Probabilities cannot be known with certainty - they must be estimated from data.

In other words, scientists use observations from the past to estimate how probable an event will be in the future.

In this training, you will learn how to estimate a probability as a relative frequency, calculated from a sample of observations.
