Reading data

Facets reads your data, matches them with your model statements, and reports how much usable data was found.

Table 2. Data Summary Report

Assigning models to "creativity.xls"

Excel Data = C:\FACETS\examples\creativity.xls

Launching Excel .... If your data is in a .xls file

Ready ....

Waiting for Excel ....

Data = C:\DOCUME~1\Mike\LOCALS~1\Temp\1980X36689.97XF3.txt

First active data line is: 1 1 1-5a 5 5 3 5 3

             Processed as: 1, 1, 1-5a, 5,5,3,5,3

Check that your data have been correctly understood by Facets



>====< is the iteration bar. It is drawn across your screen to show progress through the data.


Total lines in data file = 22

Total data lines = 22

Responses matched to model: ?B,?B,?,CREATIVITY,1 = 105

    Total non-blank responses found = 105

         Number of blank data lines = 1

Valid responses used for estimation = 105

Check that the responses matched your models in the way you expected.

Responses not matched to any model and ignored = 0

If some observations did not match any of your models. You can use Query=Y to check what happened


Point-biserial correlations are calculated if "Pt-biserial=Y".
