I need a plugin for one of the major blogging-programs (Wordpress, Drupal, Joomla, etc.), PREFERABLY Wordpress.
With this plugin, it should be able for the admin of the site to create a poll, with multiple choices.
Let's say you have the question: "what is 2 times 3?", and you get 3 different answering opportunities:
The question is in the category "math", and in the sub-category "multiplication".
Now, as a user on the site, you have been correct in the polls about "multiplication" 45% of the time. Therefor, your vote in the poll counts 0,45 points (would count 1 if you are always correct).
A lot of different users will vote, som good at multiplication and others bad at it, and the different options, a), b) and c) will get different amount of votes all with different weight, based on the voters average chance of being correct in the individual sub-category.
Now, later it is found out that the correct answer is b), 6, and all those who voted for option b) will get a correct score, meaning that their future votes in the subcategory of "multiplication" will be weighted more heavily - for instance increasing your votes weight from 0,45 to 0,5.
The plugin will have to make it possible for the admin to create categories and subcategories and the polls in them.
The weighted results of the polls will have to be available to everyone visiting the site, but only registered users should be able to vote with their respectable weights.
The result of the poll would be shown in procent;
If answer a) has two voters with weights of 0,1 = combined weight of 0,2
and answer b) has 10 voters with weights of 0,9 = combined weight of 9
and c) has one voter with a weight of 0,8 = combined weight of 0,8
a) would get 0,2/10 = 0,02 = 2%
b) would get 9/10 = 0,9 = 90%
c) would get 0,8/10 = 0,8 = 8%
Thanks in advance, Alexander.
