Probability density function¶
Speak to a probability of a given range of values happening.
The probability distribution function gives you the probability of a data point falling within some given range of a given value.
- (-σ; 0) = 34.1%
- (0; σ) = 34.1%
- (-2σ; -σ) = 13.6%
- (1σ; 2σ) = 13.6%
- etc...
Probability mass function¶
When dealing with discrete data, we use probability mass function. It basically is a histogram that shows how many times each event has happened.
