correlation {Ans: A pattern of two events occurring around the same time. This pattern can be coincidental, and happen by chance, or causal, when one event causes the other event to occur.}non-linear {Ans: An expression or equation that is illustrated by something other than a straight line.}explanatory variable {Ans: The variable that may be the cause of some result.}relative frequency {Ans: A way to approximate a probability by taking the number of times an event occurs divided by the total number of trials.}dot plot {Ans: A graphical representation of data that plots the frequency of data along a horizontal line.}cubic {Ans: An expression or equation of degree 3.}degrees of freedom {Ans: A number whose value is one less than the sample size, when conducting a hypothesis test.}condtional probability {Ans: A probability that depends on the occurrence of an earlier event.}association {Ans: A pattern or relationship between two variables.}the principle of equality {Ans: If you perform equivalent operations to both side of an equation, the result will always be an equivalent equation.}skewed left {Ans: A skewed distribution where the long tail of the curve is on the negative side of
