- Ok, time to put in my two cents worth.
-
- In his excellent Statistics text _Statistics: A computer integrated
- approach_ (ok, so I'm a stat nut), Alan Kvanli used data from a study which
- was conducted at Brookhaven Univesity. In that study 1250 graduate student
- records were examined and the following information was recorded and
- analyzed:
-
- VGRE: Verbal GRE
- QGRE: Quantitative GRE
- GRGPA: Graduate GPA
- UGGPA: Undergrad GPA
- LSINDEX: Score on Life Satisfaction Index Questionnaire
- AGE: Age
- SEX: Sex (0=Male, 1=Female)
- MARITAL: Marital status (1=Never Married, 2=Ever-married,
- 3=Divorced, 4=Remarried)
-
- Of interest here, of course, are the first four variables.
-
- Without going into a lot of the subject matter of the book, let me
- basically present the conclusions that are relevant to this discussion.
-
- Dealing with a Multiple Regression model, Kvanli developed the
- following equation from a subset of the sample data (I've entered the data
- into my computer in its entirety, and the model that Systat generates is not
- very far from the one Kvanli presents). Here is the equation he developed:
-
- Y^=-.395+.0031X1+.00059X2+.4457X3
-
- In which X1=VGRE
- X2=QGRE
- X3=UGPA
-
- And of course the variable of interest (Y) is the GRGPA.
-
- Presumably a similar model is in use at most Universities. Is the
- use of the GRE valid???
