Exploratory Analysis
The first row of the table indicates that 67_alienation depends, directly or indirectly,
on ses only. The total effect of ses on 67_alienation is –0.56. The fact that the effect is
negative means that, all other things being equal, relatively high ses scores are
associated with relatively low 67_alienation scores. Looking in the fifth row of the
table, powles71 depends, directly or indirectly, on ses, 67_alienation, and
71_alienation. Low scores on ses, high scores on 67_alienation, and high scores on
71_alienation are associated with high scores on powles71. See Fox (1980) for more
help in interpreting direct, indirect, and total effects.
