Two-facet partial credit/rank order: Sportscasting

In 1988, the abilities of seven baseball announcers were ranked on 6 items of sportscasting performance (Polskin, H., 1988, The best sportscasters in baseball. TV Guide, 30 July). These are discussed in MFRM Chapter 12 (but analyzed by a different method). A satisfactory method of analyzing rank ordered data is to treat each ordering as a test item, and the numerical rank placement as partial credit grades on that item.

Facets specifications and data (in file Sportcas.txt):

Title = Rank orderings of Sportscasters (TV Guide July 30 1988)

facets = 2 ; two facets: sportscasters and ranking items

arrange = 1m,N ; arrange sportscasters by measure-descending, and all facets by element number

positive = 0 ; no facet is positive - lower number=higher rank

noncenter = 2 ; center sportscasters

unexpected = 2 ; report rankings, when standardized residual >=|2|

model = ?,#,R7 ; sportscasters, and rankings each with its own scale ("partial credit")

labels =

1,Sportscasters ; name of first facet

1=Vin Scully ; names of sportscasters

2=Bob Costas

3=Al Michaels

4=Skip Caray

5=Harry Caray

6=Ralph Kiner

7=Steve Zabriskie

2,Items of Performance ; name of second facet

1=Calling the game ; names of items on which sportscasters were ranked

2=Working with analyst ; Note: all items will have the same score and calibration

3=Broadcasting ability ; if data are complete, i.e., every sportscaster ranked on every item

4=Quality of anecdotes

5=Knowledge of baseball

6=Enthusiasm level

data = ; each column = item, has 7 rankings

1,1-6,1,3,1,1,1,4 ; first datum is 1,1,1 = Vin Scully - Calling - Rank 1

2,1-6,2,1,3,2,3,3

3,1-6,3,2,2,3,4,2

4,1-6,4,4,4,4,6,6

5,1-6,5,7,5,6,5,1

6,1-6,7,6,7,5,2,7

7,1-6,6,5,6,7,7,5

dvalues = 2, 1-6 ; put 1-6 in data facet 2 of all data records

1, 1,3,1,1,1,4 ; first datum is 1,1,1 = Vin Scully - Calling - Rank 1

7, 6,5,6,7,7,5

The equivalent analysis using Winsteps is:

Title="Sportscasting"

NI=6

Item1=1

name1 = 8

codes=1234567

uscale=-1 ; reversed to give highest measure to lowest score

Calling the game
