Comments: To: "Ohlott, Patty" In-Reply-To: <49B2F333F1CAD411B80100B0D068172204A514CB@gsoms01.ccl.org> Content-type: text/plain; charset=us-ascii Patty, Based on your measures, I don't see why bivariate correlations and multiple regression can't be used, but first standardize your variables (run "Descriptive Statistics=>Descriptives" and check the "Save standardized values as variables" box), since each skill (independents) may have its own distribution, and your performance measure (dependent)is a three point scale. I do this when analyzing 360 evaluations.

The skills consist of 21 continuous scales (range 1 |to |5). The overall performance measure is ordinal - high, medium, low. The |sample size is >1000. We want to see which of the skills are most related |to performance. She has tried SPSS's PLUM/ordinal regression procedure but |is having some trouble interpreting the results - from the parameter |estimates given the software seems to be treating the continuous variables |as ordinal as well. Is this the proper procedure to use? If so, any |advice/insight on interpreting the results? If not, are there others you |would recommend? Recommendations of any reference materials that might be |helpful would be appreciated also. She is on a tight deadline so if anyone |can help, the sooner the better. | |Many thanks in advance! | |Patty | |Patricia J. Ohlott |Senior Associate |Center for Creative Leadership |P.O.
