Linear Regression

  • correlation: is there a relationship between the variables?
  • regression: what is the line that best fits the data?
  • slope: rate of change of a line
  • y-intercept: where a line crosses the y-axis
  • line: describes a precise one-to-one relationship between each x value and each y value
  • regression: a technique to find a best fitting line to a data set
  • regression line: line found by regression
  • y^p: predicted value of y
  • distance: y-y^p. error of the line fit. best line will have the least amount of error
    • total squared error
