Analyzing
MOARS Peer-assessment Data with FACETS |
|
|
|
Step 1 Download
and install the MOARS audience response
system onto your web-server and install the Peer-assessment Add-on. |
|
|
|
|
|
Step 2 Download
and install FACETS
(paid version) or MINIFAC
(free version). |
|
|
|
Step 3 From the
MOARS output, save the “Facets_Rating_Specification”
file and the “Facets_data” files in the
same directory/folder. The “Facets_Rating_Specification” file contains the
instructions (specifications) telling the FACETS software how to read
the data file. The “Facets_data” file
contains the data. You must have both files saved in the same directory
so that FACETS knows where to look for the data. It is a
good idea to start a new directory for each data set so that the files
for different analyses don’t get mixed up. I do not recommend saving
everything to the desktop, that’s asking for trouble. |

|
|
Step 4 Drag and
drop the “Facets_Rating_Specification” file
onto the FACETS icon on your desktop. FACETS will start and prompt for
“Extra Specifications”. Click “OK” to continue the analysis. Next, you
will be prompted for a filename to save the output file to. I suggest
just using the default, which just appends “.out” to the specification
filename. Click “Open” to save the output file and the FACETS analysis
will run. |

Step 5 The output
file will open. This is a text file that contains the most important
results. There are other outputs available from the menus in FACETS,
including some graphs and Excel output options, but the most important
stuff is all in the output text file. Quick Guide to Understanding
