Sample Notation : Mean (x̅) , Proportion (p) , Standard Deviation (sx), Variance (sx2) , Population Notation : Mean (μx), Proportion (π), Standard Deviation (σx), Variance (σx2), Parameters : associated with population , refers to measures used to describe the distribution of the population we are interested in, Probability : can take a maximum value of 1, can be expressed as a proportion , can be expressed as a percentage , a quantitative measure that is a particular event will occur  , p = number of times an event will occur / total number of events, Sampling Error: the discrepancy between a sample estimate of a population parameter and the real population parameter, σx̅ or SE = σ / √n, the standard deviation of the sampling distribution of the mean, It describes how much variation there is in the theoretical sampling distribution of the mean,
