4. INITIAL THOUGHTS IYNT GRADES
ABOUT THE PROBLEM
IYNT GRADES
An upwards of four thousand grades that Jurous have given in Science Fights of previous four IYNTs can reveal propreties and hidden regularities of the IYNT grading. Suggest an interesting hypothesis that concerns the IYNT grades and test it with real data from previous IYNTs.

8. Useful information from the Results
INITIAL THOUGHTS
Useful information from the Results
2 or 3 teams in each room
n=the number of teams
n=0 (mod 3) → 3 teams in each room
n=1 (mod 3) → 2 rooms have 2 teams, other rooms have 3 teams
n=2 (mod 3) → 1 room has 2 teams, other rooms have 3 teams
semi final?
in 2015 & 2016 → yes
in 2013 → no
reason? team number
V (victory)
0 or 0.5 or 1
basic thought (the first one -1, the second one -0.5, the third one -0)
=1.78<2
=0.70<1
THE SCORES ARE NEAR EACH OTHER, THE VICTORIES ARE THE SAME ↑

9. Useful information from the Results
INITIAL THOUGHTS
Useful information from the Results
Average score
basic thought-1: ( )/10=19.4 ≠ 19.2
basic thought-2: ( )/8= ≠ 19.2
why?
replace the max and min with (max+min)/2 (26+17)/2=21.5
calculate the average of (n-1) numbers ( )/9=19.2
Rank
first sorted by SV
then sorted by TSP

CONCLUSIONS

27. CONCLUSIONS With the application framework, IYNT Grades
can be calculated much faster than just
calculate it by ourselves

FURTHER DISCUSSION

29. FURTHER DISCUSSION
Since it might be impossble for us to type in all the scores
correctly, the changing system which support alterations may
be useful
A better output format is needed

32. Properties and hidden regularities
INITIAL THOUGHTS
Properties and hidden regularities
THE MOST IMPORTANT: The score as an opponent
(since the score is ranged from 1 to 30, half of the total score in each Science Fight)
THE MOST EASY TO GET: The score for self introduction in the opening ceremony
(As you can see, most of the teams got full score and other
teams get 9 or 8)
IYNT Grades

33. Properties and hidden regularities
INITIAL THOUGHTS
Properties and hidden regularities
THE SCORE: Made up of scores as a reporter, the scores as an opponent and the scores as a reviewer In each Science Fight.
THE RANK: Sorted by the sum of sum of victories. If the sum of victories is the same, the rank should sorted by the total of each average score, the total of average score as a reporter, and then the total of average score as an opponent.
