  3. Multiple Regression with Multiple Quantitative Predictors
  4. Semi-partial Correlation (ΔR2)
    • Summary notes for chat: Notes 8c Regression Semi-partial Correlation 
    • Detailed notes: Read Notes 8b page 5 section entitled "ΔR2, Semi-partial Correlation, and the Partial F Test of ΔR2"
    • Video: ΔR2 Discussed and Illustrated in SPSS ΔR2 Notes used in video; Test Score Data (in SPSS format) used in video
      • (Note: SPSS syntax offers easy way to obtain several ΔR2 values and F ratios simultaneously: change Method=enter x1 x2 x3 x4 to Method=test (x1) (x2 x3) (x4). For Video data above, this command change produces summary output: "/METHOD=ENTER Study_Time IQ Griffin Moore" to this "/METHOD=TEST (Study_Time) (IQ) (Griffin Moore)" Add video segment to video above demonstrating this.
    • Table of Critical F-ratios: Critical F at .05 and .01
