e.g. the effectof fire size (Z) on the relationship between # of firemen (X) and damage (Y)
e.g. the effectof education (Z) on the relationship between age (X) and income (Y)
Step 1 – Construct the zero order cross-tabulation table.
The Marginal (Zero-Order) Table
Step 2 – Calculate the zero order measure of association.
e.g. Lambda = 40/40 – 30/40 = .25
Step 3 – Construct the first order partial tables.
The Marginal Table
Partial Table for Young
Partial Table for Old
Step 4 – Calculate the partial measures of association
Total Young Old
Lambda .25 .00 1.00
Step 5 – Form the conclusion
Since the partials have changed from the marginal measure, one getting stronger and the other disappearing, we would say that we have specified the zero order relationship as probably intervening (i.e. we are born into a sex, grow older and as a result, join a political party).
