Probability Distributions
Functions describing the probability of different outcomes.
Just because something is random does not mean every outcome is equally likely. Probability distributions describe how likely each possible outcome of a random event is.
To get started, familiarize yourself with these three probability distributions:
- The normal distribution (continuous processes with a central tendency)
- The Poisson distribution (counts)
- The binomial distribution (ratios, proportions, binary data)
The video below introduces these and provides some intuition.
There are many other useful probability distributions which we will learn about as we progress, but these three form the starting point for many analyses.
