A variable (e.g. height of a flipped coin) that can take any of infinitely many values

A variable (e.g. number of heads flipped) that can take only one value

A plot of the frequency of all of the discrete variables for all the possible values that the variable can take, where the area underneath is equal to 1

X ~ N(μ, σ²), where X is a normally distributed variable, μ is the population mean, and σ is the standard deviation

Has parameters μ (population mean) and σ² (population variance), Is symmetrical about the mean, Mean = Median = Mode, Is a bell-shaped curve, Has asymptotes at the x axis, Has an area under the curve of 1, Has points of inflection at μ ± σ
