There are three different types of this; positive, negative or none (11) 4. This is the more accurate of the two correlation coefficients (4) 5. The value of the b in the LSR represents this (8) 7. This variable is the one that you measure in an experiment. On a scatter graph this will be plotted on the y axis (8) 8. The value of b in the LSR tell us that for every increase of one in x, the increases by an ___ of b (7) 9. 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) Down 2. We could choose to use this is the data were presented on different scales (4) 3. The ___ moment correlation coefficients is a measure of the strength of a linear association between two variables (7) 6. Values of the correlation coefficient between -0.2 and -0.7 are said to be ___ negative (8) 10. The formula for proving the value of PMCC can be found on this page in the formula booklet (4)
