  • The least squares regression line is the statistical name for this (4, 2, 4, 3)
  • The value of the a in the LSR represents this (1, 9)
  • The value of the b in the LSR represents this (8)
  • There are three different types of this; positive, negative or none (11)
  • This is when we estimate values from outside the data range (This is less reliable) (13)
  • This is when we estimate values from within the data range (this is more relaible) (13)
  • This variable is the one that you have control over and can manipulate in an experiment. On a scatter graph this will be plotted on the x axis (11)
  • This variable is the one that you measure in an experiment. On a scatter graph this will be plotted on the y axis (8)
