Verification

Why is this flagged for verification? All of the text and data is derived from the IPhO website (external link given), specifically the sections about statutes, history, and statistics. Seems like the flag for verification is inappropriate.

Prizes

"The contestants who get more than 90% of the mean value receive first prizes. The contestants who obtain between 78% and 90% receive second prizes. The contestants who obtain between 65% and 78% receive third prizes. The contestants who obtained between 50% and 65% receive commendations called honourable mentions. All other participants receive certificates of participation."

This sounds extremely wrong. Assuming a normal distribution, well over 50% of the competitors would get firsts. Does it not mean the top 10% receive firsts, etc? This would be far more normal for an olympiad. Andymc 19:52, 30 April 2006 (UTC)[reply]

It may sound wrong, but it is precisely correct. "Mean value" refers to the mean value of the top 3 scores, not all the contestants' scores. So anyone within 90% of the top scores is a gold medal winner. Referring to the Statistics PDF available on the IPhO website shows how this works in practice. In a typical year there will be around 8 to 10 gold medal winners, and around half the contestants will receive either a silver or bronze medal or an honourable mention at least. This is considered fair because there will be over 100 contestants in a typical IPhO and they do not want to reward only a small number. Incidentally, the distribution of scores is probably not a normal distribution, though that might be interesting to study further.

I expect the Physics Olympiad is similar to the Chemistry Olympiad - in that, approx 10% of contestants get gold medals, the next 20% silver and the 30% after that get bronze. Gingekerr 11:19, 7 June 2006 (UTC)[reply]

I think the distribution of medals stated above is for Asian Physics Olympiad, and by mean value, it refers to the mean value of the top 3 scores. 90 % of this mean value sets the lower bar of Gold Medal. In International Physics Olympiad, they rank the scores and cut the number of gold medallists at around 5% of the number of participants, then the cut off will be the lower bar for a Gold Medal.

I was involved in the prize decision process in 2013, and the above is all more or less wrong. The current rules are found here (§6), and as far as I recall it was exactly the same in 2013. As stated above by some unsigned editor, the contestants are ranked from best to poorest score. Then, a cut-off mark is decided on so that the top 8% of participants will be are awarded Gold, a further 17% Silver (for a total of 25% Gold and Silver), an additional 25% Bronze (50% total), and 17% Honourable Mention (67% total). The cut-off marks are set as integers though individual problems are marked to 0.1 or 0.05 marks. The integers are chosen to make the totals exceed the stipulated values (8%, 25%, 50%, 67%) as little as possible. This is done based on Marker's marks only (markers are employed for this job by the host country). Subesquently, the national leaders negotiate individual marks with the markers, typically focussing on raising the marks of participants just shy of one of the cut-offs, and on fixing obvious oversightsand language-related misunderstandings. Thus, based on the final marks after this moderation process, there will be a little in excess of 8% Gold medals, etc.--Nø (talk) 16:16, 4 June 2018 (UTC)[reply]

Iran next year?

In the light of recent developments, does anyone know if there will even be an Iran to hold the Olympiad next year? Gingekerr 11:21, 7 June 2006 (UTC)[reply]

Should be, at least I'm going there as a member of team Finland. Check http://www.ipho2007.ir --Heikki m 21:20, 8 May 2007 (UTC)[reply]

Hmm

Someone stated that the 2017 olympiad will be held in "Moldavia", that's a region in nowdays Romania and Moldova, think that the link and flag should be changed to "Moldova" (http://en.wikipedia.org/wiki/Moldova). Horhalau (talk) 12:13, 5 May 2009 (UTC)[reply]

Links

Would it be better to move the links to the organizers for each of the years 1998 to 2013 FROM an "External links" section INTO a new column in the table "List of past and future olympiads"?--Nø (talk) 14:37, 13 February 2012 (UTC)[reply]

Copyright violation

These three diffs are copyright violations, and needs to be deleted from the history: 1 2 3

This have seriously crippled this article. — Preceding unsigned comment added by Heb the best (talk • contribs) 14:03, 8 December 2018 (UTC)[reply]

I think we need documentation to show that it is indeed copyright violations - but before we can get that, we need the material to be properly sourced in the article, and till that happens I guess it must be removed all the same. I don't think the edits should be removed from history unless the violation is documented.--Nø (talk) 19:48, 8 December 2018 (UTC)[reply]

There is no doubt. See this. Also, compare the URL provided with the three edits (the one about the scoring system have been updated since then). Heb the best (talk) 14:38, 9 December 2018 (UTC)[reply]

Indeed, there's no doubt – please see below. Kudos to Heb the best for picking this up! Justlettersandnumbers (talk) 17:53, 9 December 2018 (UTC)[reply]

Extra information in the table

I think we need to mention about the 2020 IdPho and the 2017 "uncertain" winner--LostCitrationHunter (talk) 07:39, 19 November 2021 (UTC)[reply]
