CHAP7. This data file based on the values from Table 7-1 in Chapter 7.  This data has properties consistent with the table and can be used to replicate the analyses shown in Keppel.  Variable A has four levels, representing the level of inter-trial interval between trials.  The outcome was the number of correct answers.

Chapter 12

CHAP12. This data file was derived from Table 12-6 from chapter 12.  Keppel provides summary data, but not the individual raw data, for this example.  This is a data file that closely conforms to the results illustrated by Keppel.  The results using this data file will not be exactly the same as those shown in Keppel, but they will be very close. 

Variable A is three levels of treatment, 1 is control, 2 is positive, and 3 is negative.  B is a second independent variable and has three levels, 1 = low F & low E, 2 = High F & Low E, 3 = High F & High E . The dependent variable is the memory score.

CHAP17w. This is the wide version of the data file is from Table 17-7 from chapter 17.  Subjects perform a digit cancellation task under one of 3 conditions (representing variable a).   The task is repeated for four trials, indicated by score1, score2, score3, and score4.  The within subjects factor is represented by the four scores score1-score4.

CHAP17n. This is the narrow version of the data file from above.  It is constructed by reading the data file above, and running the following program.  In this narrow version of the file, the trials are represented by the within subjects variable b and the score on the trial is represented by the variable score.

VECTOR Vscore = score1 TO score4.
LOOP b = 1 to 4.
-  COMPUTE score = Vscore( b ).
-  XSAVE OUTFLIE="chap17n.sav" / KEEP s a b score .
END LOOP.
