    • correlation: a measure of the association between numerical values.
    • interpolation: explanatory variable for the prediction lies within the given data set
    • extrapolation: prediction is outside data set
    • r = 1 thus a perfect positive corrolation
    • r = 0 thus no linear correlation
    • r = -1 thus perfect negative correlation
    • correlation does not equal causation
    • coefficient of determination: percentage of the response variable that can be explained by the explanatory variable
