Hey Korn,
I am just reading a nice book to motivate me writing my thesis. It is about organizing creativity. One phrase in particular struck me there: "Incompetent people don't ask for help TO DO it but either none at all or for solutions". It so happens that your last post somehow perfectly matches this phrase.
I don't know what your thematic map should reflect or what you did besides that, but the following approach might have been better:
1. know yourself what a strategy is (it is not some vague concept of winning, but some well defined "set of actions maximising utility over any other sets of action" – this sure is game theory, but what else is Diplomacy than a game?). you could have then framed your strategy question better on subsequent levels (play always truthful, tit for tat – which tends to work best in purely rational environments, only beatable by "meta-gaming", and serves as a nice test for the rationality of players – always lie, stab after x-moves, stab if your ally is 2-times stronger than you, …). That you didn't get many strategies in your answers should be a warning.
2. If you were interested in measuring the importance of territories, define in what light. And then go and measure it by your own.
a) sample a set of games (for a pretest 10 should be sufficient, for an actual survey, probably 100 will do)
b) measure how many times a territory has been occupied by the winner, how many times it has been occupied by units, how many times it has been fought over, changed belonging, etc… you'll probably finding something that is necessary, if you thought about it.
c) find something to correlate your measurements against, like occupation vs. number of connections in on turn or two turns, distance from supply centers, etc… there is enough.
d) THEN, take a survey, ask players how often they have played, how often they have won, how often drawn, and what are their opinions about the top 5 most important territories…
e) check whether your somehow deductively generated importance measures and tests correlate with inductively generated estimates by players. Draw two maps if the results are interesting: How the players see the game, how the data sees the game…
3. Use the import/export function in googledocs to 1st: export the g-spreadsheet that has already and automatically collected the responses to your form to your computer (preferably as .xl…-file) and 2nd import the spreadsheet into excel (or directly into your mapping software). It takes up maybe 3 min to read it up completely in the googlehelp section and takes another 10 secs to execute the procedure. You could then enjoy much of your time analysing your results (which you should as it is rather complicated to rank the many views you received adequately as you have to account for the mean rank attributed AND the noise across the answers, if u were to truly find out something, you might like Aldrich and McKelvey 1977 to get an easy start. Also I wouldn't use excel, but that is because I suck in excel).
