 THREE STEPS1-SIGNIFICANCE OF THE ASSOCIATION The relationship between X (feelings for

blacks) and Y (support for BNP) is significant at the 0.05 level (we can reject the null hypothesis of no association).

2-DIRECTION OF THE ASSOCIATION The b coefficient of -0.219 is negative,

indicating that the people who have positive feelings towards black people tend to have lower levels of support for BNP.

3- MAGNITUDE

3-MAGNITUDE OF THE “X” EFFECT For every point increase on 0-10 scale in X

(positive feelings towards black people), the level of support for BNP (Y) will decrease by 0.219 points on the 0-10 scale.
