Discrete Random Variable
- We know what the different results are while throwing a dice (1,2,3,4,5,6), we get each of them with a certain probability
Key concepts
This is goign
- Mean
- Variance
- Population vs sample
sigma = 5.83^(1/2)
mu = 3.5
mu + sigma
mu - sigmaFormulae
Covariance
if then
- Heterogeneity is the worst
