bivariate data

Cards (8)

  • 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
