Type 1 Error
Rejecting the Null Hypothesis when it was true
When is a poisson distribution used?
When the number of trials is large and the chance of success is small
Type II Error
Failing to reject the null hypothesis when it was false
Non-Constant Error Variance
Non-Independent Errors
Non-Linear Residual Plot
Not Normally Distributed
Coefficient of Determination r^2
The proportion of y variability accounted/explained by x
Correlation Coefficient r
Linear correlation between x and y, direction of the relationship between two variables
Central Limit Theorem
As the number of random variables being averaged increases the distribution of the average will approach a normal distribution. As Sample size increases the standard deviation decreases
