The least squares regression line is the statistical name for this (4, 2, 4, 3) 4. 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) 5. The value of b in the LSR tell us that for every increase of one in x, the increases by an ___ of b (7) 6. This is when we estimate values from outside the data range (This is less reliable) (13) 9. Values of the correlation coefficient between 0.7 and 0.9 are said to be ___positive (6) 10. This is when we estimate values from within the data range (this is more relaible) (13) Down 2. The value of the b in the LSR represents this (8) 3. The formula for proving the value of PMCC can be found on this page in the formula booklet (4) 7. The value of the a in the LSR represents this (1, 9) 8. There are three different types of this; positive, negative or none (11)
