It is a common observation in many real-life events (such as examination results, corporate performance grades etc) that data tends to cluster around a mean (average). In probability theory and statistics, the normal distribution or Gaussian distribution is a continuous probability distribution that describes data that clusters around a mean or average, and this is how the graph looks.
Inspired by the bell curve model, Team GDC analyzed the voting patterns of participants. We filtered out the spikes and anomalies (at the fringes) caused by false/maliciously engineered votes or lazy applicants who dropped out mid-way. Thus we were able to determine the number of votes (a band) that would determine ‘average’ performance’. If we marked this band as the ‘mean’, we could now move up/below the mean, assigning voting bands (a range of votes) where the performance could be considered below (or above) average, and following the same rational identify those who did poorly or excellent (compared to the median score of votes).
This is a kind of relative grading principle, which helps us neglect the ‘errors’ that otherwise creep in due to a few extra votes (duplicates from known friends) or a few misses (emails not confirmed). We are not in a position to share the bands, cutoff scores etc, and needless to mention the decision of the Jury is going to be final.
Hey guys while the jury is crunching numbers & roller coasting votig graphs…here’s something for all the contestents..
How often do we get to see 2000+ people under one roof who share the same passion & live the same dream???
Most of us haven’t met but we definitely know each other…we share our lives beyond work. Let’s not lose this opportunity we’ve got to…LIVE and SHARE our passion…and not disintegrate into oblivion after this challenge is over.
This group is for all the travel freaks…nerdy bloggers…and psycho photographers to share their talent and experiences.
So next time you want to travel somewhere… learn a photography trick or even buy a camera…or need some appreciation or critical comment on your blogs…you know where to knock (for sure not under the belt ) = }
Who the hell needs travel planners…photography books…or publishers …this group will be self sufficing…we are ‘PHO-TRA-GGERS’!!!
P.S.- We are not going to discuss Cedia TGDC in this group (though we thankfully owe our existence to it)…this group is not about competition but to reach out to people who share common interest.

Wow! This surely reminds us about our MBA - Quantitative Techniques course! And not to forget a similar curve, for each of our course grading. Now, the wait for the ‘grades’.

From Relative Grading in b-schools, CAT, engineering to now RGs in competitions too! Life never lets you forget that the whole of life is nothing but RG!
I love the detail you guys are getting into with this though.

A very bright and cheerful goodafternoon to the TGDC Jury working away on a Sunday to bring the results out to us contestants at the earliest possible.
Yours surely is not a position of envy from where I am sitting. No matter how many checks and balances you employ to filter the good from the bad and the ugly, I expect some wheat grains to get thrown away with the chaff inadventently, sods law as we used to call it in England.
Your updatse are surely much appreciated. With so much hard work that the Jury is putting in, I trust the you to do maximum justice to all the contestants.
All the best for compiling the results,

I was interested in it and i thought few others would like to Refresh =
The Gaussian distribution is named for Carl Friedrich Gauss, who used it to analyze astronomical data and defined the formula for its probability density function.
The normal distribution was first introduced by Abraham de Moivre in an article in the year 1733 which was reprinted in the second edition of his The Doctrine of Chances, 1738 in the context of approximating certain binomial distributions for large n. His result was extended by Laplace in his book Analytical Theory of Probabilities (1812), and is now called the theorem of de Moivre-Laplace.
Laplace used the normal distribution in the analysis of errors of experiments. The important method of least squares was introduced by Legendre in 1805. Gauss, who claimed to have used the method since 1794, justified it rigorously in 1809 by assuming a normal distribution of the errors. The fact the distribution is sometimes called Gaussian is an example of Stigler’s Law.
The name “bell curve” goes back to Esprit Jouffret who first used the term “bell surface” in 1872 for a bivariate normal with independent components. The name “normal distribution” was coined independently by Charles Sanders Peirce, Francis Galton and Wilhelm Lexis around 1875.
Is it true that =

Not sure if you should be penalizing someone who canvassed and got a lot of votes early in the collection period and then put his feet up and relaxed… Or the opposite… Eliminate fraud (definitely) but timing of flow of (valid) votes shouldn’t really matter.

Like Supreet said, i dont envy the work of the jury at all. Sai and me have gone through a lot of the profiles and so many are deserving!!
keep up the good work guys!!

We kept hearing that votes are not the only criteria. This also meant that they “definitely” are one of the significant factor.
We trust the jury for picking up the right people for this contest.
The goal for Mitsubishi & TDGC team is most likely to get media attention, get cedia heard and popular. In the process they definitely collected the data of several people who are interested in cedia and the driving experiences.
Not sure if a standard logic will do the justice to the contestants, but we are sure the jury will!
:o) Hope for the best.

Keep up the good work guys. This looks like a good bell curve!! On another note, shortlisting from 1000+ applications is not an easy task, so Jury would need some cans of RedBull I am sure you guys have some stacked next to workstations! All the best.
