About this topic
Before you begin
Model counts and waiting times with Poisson and geometric distributions, including their conditions and properties.
Learning goals
- Choose and use Poisson and geometric models, including their means, variances and conditions
Syllabus statements covered
- Include: use of Poisson distribution Po(μ) and geometric distribution Geo(p) as probability models, including conditions under which each distribution is a suitable model; mean and variance for Poisson and geometric distributions; additive property of the Poisson distribution.
