Doesn't look like a dolly parton distribution to me...
This is an interesting thread. I would not have figured that the board's population skewed as young as it appears to in the results display.
Big thanks to the OP, btw, for putting 30 in such a generous slice of the categories. It's rare to find 30 at the tail end of a mid-20s category and not at the front end of a mid-30s category. Makes me feel good!
Just what I thought -- I was expecting a peak around 21, and another in the mid-thirties.
Yeah, I just noticed that, actually. Some of your categories/ranges are quite a bit smaller than others, which makes interpreting the distribution from the graph somewhat misleading. I hear you about how there's a big emotional/maturity difference among certain age ranges that is much more significant than the numerical age range would imply. But even still, I think it would be more statistically sound to have uniform ranges.
Agreed. I thought (hoped) that by doing it this way I could milk the most information from the data -- sizing the small ranges so they can be summed into the 'appropriate' size for the statistically correct histogram. In Excel it is looking quite normal, which is not what I really expected (or desired). Self selection bias amongst the younger members? ~ H
I just think it's your survey design that's the issue. You should've designed a poll with uniform age ranges. It's not the poll-maker's job to tweak the data input mechanism in service of a hypothesis; it's the poll-maker's job to design a sound poll, and then interpret the data that comes out of it. Like I said, and as we seem to agree: there are a lot of sticky wickets here, because certain age differences feel a lot "bigger" than others. No one would argue, for instance, that there's a world of difference between a 20-year-old and a 25-year-old that isn't equalled in the difference between a 60-year-old and a 65-year-old. But that's the sort of interpretation or theorizing you shouldn't be trying to bake into a poll. All you want with this poll is a histogram of ages by uniform range. The analysis comes afterward. Anyway, keep on keepin' on. The poll results are interesting, even if they are a bit dicey.
you're probably fine just collapsing the categories.
It would be interesting to see the age range in different sub forums.
^^^Late 50-something here. But I still remember my first 39th birthday ... and the 5th 39th ... and the 10th 39th ... and the 15th 39th ...
I just voted. I'll be turning 68 on Thursday.
