1. Causal Path Example Hourly Wage on Educ 90, Job Tenure, Sex, Full/Part-time Work Hourly Wage Tenure Full/ Part Sex Educ 90 A A A B B C D A C

2. A : Add Betas from Full Model Educ90 – Hourly Wage Tenure - Hourly Wage Full/Part - Hourly Wage Sex - Hourly Wage Use MR Handout for Nov. 16thMR Handout for Nov. 16th

3. Add Betas from Partial Models B: Partial Model –Educ90 – Full/Part –Sex - Full/Part C: Partial Model –Full/Part – Tenure –Educ90 - Tenure D: Partial Model –Sex – Educ90

4. Do Path Calculations Calculate all direct and indirect causal effects on DV Hourly Wage The product of indirect effects is added to the direct effects for each IV. Example: Educ90 –Direct.350 –Indirect (through Tenure).013x.259 =.003 –Total Causal Effect =.350+.003 =.353
