Re^2: Perl Developer Survey 2017 results are available (emacs less popular)

Come on, the math is not hard here. The question allowed multiple responses and in one case the division was done using the number of responders instead of using the number of responses.
And you got your conspiracy exactly backward. The result was to artificially inflate the percentage reported for emacs.
$ say '85+65+78+519+355'
1102
$ say '85/11.02,65/11.02,78/11.02,519/11.02,355/11.02'
7.71324863883848
5.8983666061706
7.07803992740472
47.0961887477314
32.2141560798548
$ say 138/11.02
12.5226860254083
So just drop emacs' popularity from the reported 16.25% to the correct 12.5%.
All that is left is to figure out if the mistake was motivated by the preparer being an emacs fan or because they felt sorry for emacs fans and whether it was intentional or accidental. q-:
Update: Oh, and the percentages reported for Notepad++, Eclipse, and VisualStudio might well also be inflated by x1.3 (hard to say for sure since the counts were not reported for them).
Update: Though, I kind of find the 30% higher percentages more accurate. The problem was probably that they put the counts into the graph software and it is what provided the percentages. Makes me wish for a "Venn diagram" chart where the area of each shape is proportional to the number of people who chose that option and the areas of the overlaps between shapes is also proportional (to the number of people who chose all of the corresponding options).

Hi Tye
welcome back to the monastery! :)
I figured that out already, and I'm not such a fanboy that I care about the results of a bad survey.
But I care about bad math and fake news. Nowadays more than ever.
My theory is that the questions were single choice, but the other option allowed free text were multiple editors were inserted.
Anyway a decent survey would at least
- avoid opinionated choices
- publish the original data
- keep a snap shot of the original survey online
Otherwise we'll never know, that's why I give up.
Regarding venn diagram, this wouldn't be possible in many cases.
Imho the best representation is a hasse diagram.

If that is the case, the results are presented in a very bad way.
Several numbers are contradicting and percentages are taken from different totals.
And the gap - the supposed multiple votes - at all 3 questions is always about 30%.
I might have a theory what happened but I'm tired now.
Let's hope the next survey is better prepared.

You act like numbers mean something or are absolute values. They are just an invention of Western society to hold down the… blah, blah, blah… Bonk! Bonk! On the head!

It is not what things are objectively and in themselves, but what they are for us, in our way of looking at them, that makes us happy or the reverse. As Epictetus says, Men are not influenced by things, but by their thoughts about things. --

Bless St IGNUcius, holy holy holy! =)
On a more serious note: I don't care about the real percentages of editors or web-frameworks.
I care about manipulated truth!
30% of all responses covered only 3 out of 31 questions without being noted?
Seriously?

Joking aside now: this must have been a multiple-choice question. All we know is that some people use more than one IDE, while 596+ respondents only use one.

Surely you jest, brother LanX? That was almost 2 months ago. I can barely remember what I had for lunch yesterday.
There were certainly some questions where multiple answers were available, eg. "Q5 What other languages do you use?" but I don't immediately recall if the IDE question was one of them as I would not have entered multiple answers there anyway.
The survey is useful in a qualitative fashion but I agree that the results could have been better presented. It's unclear whether that's the fault of BiP or of surveyplanet.com (or both).

"I'm afraid, it looks like the results were doctored."
I'm afraid you have no qualifications and as such, have no legs to stand on. You simply don't LIKE the results. | [reply] |
