Answer to Module
3 Exercise 2
If you then draw a line, so that
the plotted points are on or as near to the line as possible, you have
the regression line.
This is a negative correlation, because
as scores on one measure go up, so the scores on the other measure go down.
You could also say that as scores on one measure go down, so the scores
on the other measure go up. If the scores are moving in opposite directions,
the regression line will go from upper left to lower right, and it is a
negative relationship.
This is also considered a strong relationship,
but not as strong as the previous one. The points are close to the line,
indicating a strong relationship, but they are not on the line as they
were in the previous example.
