Display Judging Example

At the ASCE Polar Ice Cap Regional Student Conference (PICRC) thirteen bridges are entered.  Four display judges are tasked with judging the bridges.

Task Number One:  Score the bridges appearance.

Each judge chooses then ugliest bridge as having a score of 1 and the most beautiful bridge as 10.  The judges independently do their own ranking and arrive at the following results:

PICRC Appearance Scores
Entry Joe Jane Harold Rebecca
Univ. of Snow 1 1 3 1
Glacier Univ. 5 7 4 6
Polar State Univ. 9 10 10 5
North Pole City College 10 9 8.5 10
Ice Ridge Univ. 6 7 7 6.5
Univ. of Plain Fun 3 4.5 1 3

Task Number Two:  Determine if bridge is properly identified.

Going to abet.org, the judges find the official name of the university that each student chapter comes from.  Comparing the names on the bridges to the ABET list, it is determined BY THE JUDGES AS A WHOLE that Polar State and the Univ. of Plain Fun do not have their full official names on the bridge.  In addition, the Univ. of Plain Fun and Glacier University have letters that don't meet the size requirement.  Glacier Univ. used italic letters that are the right size on the diagonal but not vertically as specified.

Penalties:    Polar State, Univ. of Plain Fun and Glacier Univ.

Task Number Three:  Poster Judging

Each judge independently scores the posters on a scale of 0 to 5.  A zero is given only if a bridge team fails to provide any poster at all.  A five is given if all 7.1.3 criteria is met.  Judges decide on their own how to score in between 1 and 5.  The following is a table of the results for the PICRC:

PICRC Poster Judging
Entry Joe Jane Harold Rebecca
Univ. of Snow 3 2 3 1.5
Glacier Univ. 2.5 4 4.5 3
Polar State Univ. 4 5 4.5 3.5
North Pole City College 4.5 4.5 5 3.5
Ice Ridge Univ. 3 4 4.5 2.5
Univ. of Plain Fun 0 0 0 0

It should be obvious that the Univ. of Plain Fun did not provide a poster.  Also note that any judge can score any bridges equally.  For example, our judge Harold is a relatively generous scorer and he has given three of the bridges the same high score.

Entering the Data and Analyzing the Results:

The Judges then gather to enter the data into the computer spreadsheet.

Check out the printout of the data entry and calculations by clicking here.

In this case there are no ties in the Ranking Score (see column near the far right of the form).  If there were, then the judges need to make a decision about what input scores to change to break the tie.

Note that, in this case, the section 7.1.2 penalties moved some bridges up and some down the rankings.  This can be seen in the far right column.  If the move is too extreme (i.e. a bridge move more than 1/4 of the way up or down the list) then the judges can alter the weight divisor until the movement on the list is restricted to a smaller value.

For the PICRC, the Univ. of Snow and Ice Ridge Univ. both moved up in the rankings due to the Name and Poster scores.  Polar State Univ. and the Univ. of Plain Fun fell in the rankings for the same reason.
