Are you already working as a software developer?

  • It's the most answered question (99.5% respondents).

  • 11% of respondents who code for less than 1 year already work as software developers.

  • 24% of respondents with 5+ years of programming experience aren't working as soft devs.

THE DSR WEEKLY DIGEST:

DSR (DataScience Room) is an effort to gather campers of all levels and specializations willing to engage in discussion, collaboration and practice of data-related projects, with preference for using FCC data.
Previous Digest
Tentative DSR site: http://evaristoc.github.io/FreeCodeCamp_DSR/


This week we continued working on the Survey 2016. @krisgesling made a first final draft of the map for Gender/Ethnicity. Other people in the room showed interest in working some visualizations. @SamAI-Software has been helping to organise the visualizations and hightlighted a few trends from the data. @erictleung is still working a final clean dataset (remember that the current dataset can be used though). @SamAI-Software and me are helping @erictleung with his work.

For those interested in working on the Survey 2016 dataset, please keep checking the repo and these links:

@evaristoc very interesting full digest :+1:

@SamAI-Software

Would you prefer to work for a startup, start your own business, work for a multinational corporation, work for a medium-sized company or freelance?

  • Almost 90% of respondents who code for less than 1 year have preferences about their job, while most of coders (76%) with 5+ years of programming experience are ready to work in a company of any size and even freelance or start their own business.

Please, feel free to correct my English!

@evaristoc
@SamAI-Software can you please add legend for the grey area? If NA, I think it would be better to get rid of it, specially for the last one... BUT then keep it around, in case someone more statistically-minded want to approach your results...
Ah! I love gplot...
evaristoc
@evaristoc

@SamAI-Software

Are you planning to work on those viz in d3.js? If you think you need help, can you find someone here who can join you to make those gplots into D3? I think there is even a d3-based library that use similar styling...

Does anyone in the room can suggest something?

Sam Aiken
@SamAI-Software
@evaristoc yeah, grey is exactly for NA, sorry for no legend. But if I get rid of NA, then we cannot see how many people don't have any preferences (because survey didn't have answer "no preference"), so I keep it for this purpose

Sam Aiken
@SamAI-Software

Are you planning to work on those viz in d3.js?

Yes, for sure! But first I want to explore all data and find some interesting things

evaristoc
@evaristoc

@SamAI-Software

Nice work and nice that you are going to work on this with d3!!

About the chart... I cannot really visualize the proportions per category, specially for the least represented category. Could you find a better representation?

I would suggest a similar effect as that one made by @krisgesling:

  • the bar chart showing the differences between the TOTALS of each category, not the proportions of "prefered job", and including the NA's. The effect of NA per category was easily perceived and probably the most "shocking" result in the previous chart.
  • add 3 pie charts as companions, each representing the categories you identified and and use them to showing the proportions per segment taking complete responses only (not to include NA information).

It would be interesting to find out why the longer time programming the lower the chance that the respondent answered that question... I think it is because they already have a job??

They are only suggestions, @SamAI-Software... No need to implement them.... it would be nice to see it though...

About your previous chart (about working as a software developer): could you just substitute the legend 0-1 by "No/Yes"? Those results are interesting too...

Nice job!!

anyone want to study multilinear algebra with me?
Sam Aiken
@SamAI-Software

It would be interesting to find out why the longer time programming the lower the chance that the respondent answered that question... I think it is because they already have a job??

@evaristoc, yeah, I'm also very curious about it - will dig into that asap

Sam Aiken
@SamAI-Software

About the chart... I cannot really visualize the proportions per category, specially for the least represented category. Could you find a better representation?

Yeah, I see your point! Don't worry, right now all my visualizations are for acknowledge purpose only. I'm exploring the data and sharing some interesting facts with text & simple vizs.
But I need to add a legend for grey NA, that's totally true, but not sure how to do it in an easy way with ggplot. You said you love gplot, can you help me? :) Do you know how to add custom legend for stat_count or just add NA into legend?
Of course, I've tried to search for it, but didn't find any simple solution... R is so not user friendly!
Thanks!

Sam Aiken
@SamAI-Software
@evaristoc lol, I've just discovered that 5 questions were asked only if respondent doesn't work as a software developer, yet. I will write to @erictleung to add that info to questionnaire.
MonthsProgramming&IsSoftwareDev&JobPref(720).jpeg
NA is grey
So yeah, my yesterday's statement about "Coders with big experience have less job preferences"was wrong :(
Sam Aiken
@SamAI-Software
@evaristoc, but still, tell me please how to do custom legend or just add NA into the legend, if you know.
Quincy Larson
@QuincyLarson
@SamAI-Software great work with these charts! Yes - explore the data first, then convert to D3. I think these stacked bar charts are a good way to go for a lot of visualization, though they aren't as exciting as, say, a force-directed graph ;)
@evaristoc as always, thanks for the great weekly digest!

@SamAI-Software

  • about finding the 5 questions :+1: ! that is also the good thing about exploring the data :)
  • about just showing results: yeah. the work is still wonderful.
  • about NA: just a quick thinking... I would copy the column and substitute NA with another category instead ("if (value = NA) then (value = "NA")). Then I could have some control on that too...

@jacobborges
I am interested, although I might not be on pace for any other training at the moment... can you tell me why you are into multilinear algebra and where, how, etc is the training you want to follow?

Sam Aiken
@SamAI-Software
("if (value = NA) then (value = "NA")) @evaristoc nice idea!
evaristoc
@evaristoc
:+1: let me know if it works for you, anyway...
Sam Aiken
@SamAI-Software
For now I just don't show NA's, but later on I might come back to that issue

@SamAI-Software

About how many hours do you spend learning each week?

  • Almost half (47%) of coders with 5+ years of experience who already work as software developers still spend at least 10 hours each week learning programming.

Do we have something which looks at what strings @camperbot returns "nothing found" for on help/wiki/etc ?
evaristoc
@evaristoc
@SamAI-Software Excellent, man! Few days and you are going to exhaust all the possible questions about what can be done with that dataset!! :) :)
But really: nice...
Advice for the last one? Easy: show the proportions and look for a way to report the n per category somewhere else? Perhaps in the sub-title of the figures...
Proportions instead of total counts for this one will allow cross-comparisons (a simple way to standardise the data...)
evaristoc
@evaristoc
@SamAI-Software I was suggesting "conditional" proportions (I think it is x% | Time,SD?), not the simple ones.
