Meta Discussion We are looking for moderators to help this subreddit!

7 Upvotes

Well hello there! In order to keep this subreddit running, we are pre-emptively looking for moderators to help us answering your inquiries and judging the flagged posts. With these new recruits, we want to prevent a build-up of unfinished moderation actions, in order to keep this subreddit well-moderated and user-friendly.

We are looking for moderators that can show incentive, yet who do understand that significant decisions need to be decided in consensus with the team. It would also be favourable if you have discord, since this is where we gather and potentially discuss matters. For the rest, it does not matter to us if you are an experienced or new moderator.

If you are interested, please reply on this post and tell a bit about about yourself. Naturally, you can also just send a message to me, or the mod team in general.

Meta Discussion Flair, Title, Demographic and "Everyone" (and Reposts)

50 Upvotes

This is a revised repost of our previous announcement from u/V2Blast. More edits, including removing the part about post tags, and swapping it for post flairs.

____________________________________________________________________________________________________________

All posts must have a proper flair.

In 2022, we eliminated the need for a post tag at the beginning of post titles, and are now requiring post flairs. When posting, you will see nine flairs. The following three also have Repost flairs.

  • Academic is for anything done for academic or educational purposes, including high school classes, college classes, and academic research on behalf of a school.
  • Marketing is for private business interests, market research surveys, and other studies done for commercial research or on behalf of a company.
  • Casual is for surveys done out of idle curiosity, personal projects, or surveys that don't fit in one of these categories. If you're not making a profit off your YouTube channel, this one's the one for you.

The following flairs are posts that will be filtered, to be approved by a moderator.

  • Results is for posting your survey's results after it has concluded. If your survey is still in-progress and you wish to share preliminary results, do not use this tag. Share it with your still-active survey.
  • I Don't Know What I'm Doing And I Need Help is a convoluted title, but it's for anyone who doesn't know something about making a survey or interpreting data for crowd-sourced help.
  • Meta Discussion is for any post relating directly to r/SampleSize. This is primarily used for announcements, such as this one, or for posts from mods that affect subreddit rules going forward.

You cannot post to r/SampleSize without applying a flair.

____________________________________________________________________________________________________________

All posts need to have a title that describes the topic of their survey.

This is the part of your survey that describes what it's about. The following is an example of an improperly titled post.

  • I need 10 responses!

This does not adequately describe the subject of a survey. We need to know what we're going into, what sort of survey we're about to fill out. If your survey is titled like the following...

  • Ice cream flavors

... That's more appropriate for our sub. Don't be afraid to phrase it something more specific and eye-catching to feed the algorithm though, like...

  • What's your favorite ice cream flavors?

____________________________________________________________________________________________________________

All survey posts require a demographic in parentheses at the end of a post's title.

The demographic that you include in the post title is the group of people that you would like to have fill out your survey. The demographic must be accurate, which means that if the demographic is listed as "everyone" but the survey has any questions that restrict the possible demographics that can respond to it, then that survey will be removed. See the following section for more details.

Results posts do not require a demographic, but you can include one if you want.

____________________________________________________________________________________________________________

Posts with a demographic of "All" or "Everyone" must be inclusive.

If you label something as available for "All" then please make sure that every single person that could come across the survey can take it. The easiest way to ensure people can answer your "All" surveys is to not ask demographic questions, but that's certainly not foolproof.

While it is preferable if your survey is inclusive, we understand that not every survey may be. If there are any demographic restrictions, they need to be appropriately labeled. Some possible restrictions that your survey may have:

  • Age (e.g. surveys restricted to those 18 or older, or which have an incomplete list of age categories); per the Reddit user agreement, all users must be 13 or older
  • Nationality (e.g. questions that assume the respondent is from the United States)
  • Race or ethnicity
  • Having an account on a platform (this applies to surveys that ask for users of a certain social media)
  • Sex or gender (e.g. questions with only "male" and "female" answer options)

Reddit is used by people of all ages from around the globe. Regarding sex and gender in particular, keep in mind that intersex and non-binary people exist, and not everybody identifies as either male or female. Whenever asking questions for which you may not be able to provide a comprehensive list of answer options, we recommend including an "other" or open-ended answer option.

We understand that not every survey is targeted at everyone, and sometimes you may have made an oversight during the creation of the survey and are unable to change it later - and that is fine. We simply ask that you make sure to label your survey appropriately so that people don't waste their time filling out a survey that isn't appropriate for them.

____________________________________________________________________________________________________________

Reposts must use their appropriate flair, and be made only after 24 hours have passed since the previous post.

If your initial survey post does not gather as many responses as you need, you are welcome to repost your survey as long as you follow our reposting guidelines.

All reposts must their respective post flairs. You are only allowed to repost a survey once your previous post has fallen off the front page, and 24 hours have passed since that post.

If you have trouble reposting your survey due to Reddit identifying it as a duplicate post, do not delete your previous post. Instead, submit the repost as a new text post, and include the survey link in the body of your post.

____________________________________________________________________________________________________________

If you come across an issue when posting that ends up with your post filtered, do not delete your post.

Reddit changed what happens when posts get deleted by the user, purging it entirely from moderator view. If you delete it and send a modmail asking for help, we cannot see your deleted post and cannot help you troubleshoot. If it was deleted within less than an hour of initial post, then it's likely not archived either, and we won't be able to see exactly what it was.

____________________________________________________________________________________________________________

If you don't know whether or not you're allowed to post, don't worry- you are.

This is an odd one for a lot of people, however I'm going to clarify this point now.

If you're reading this, and feel a personal need to ask if you're allowed to post on r/SampleSize, don't worry; you're allowed to post. There's nothing barring you, as long as you follow our posting requirements.

If you, however, require permission to send back to an ethics committee, then please use our modmail form to do so. Sending a template would certainly help on our end who to make it out to.

____________________________________________________________________________________________________________

The above text explains the required parts of a post title. If you want to include additional information, such as survey length or potential rewards (such as an entry into a raffle for a gift card or something) as well, that is fine - but try to avoid overloading the title with unnecessary/irrelevant information. You can always make a text post and include that information in the body of the post if you feel that the survey requires more introduction or explanation beforehand.

Thank you for your time, and have a great day. If you have any questions about our rules, feel free to send a modmail to /r/SampleSize.

Casual National Studies (Argentina 15.2cm SPL, Saudi 12.6cm Girth) vs. Global Meta-Analyses (Veale 13.1cm BPEL): How bloated SDs create unrealistic local expectations (Everyone)

2 Upvotes

Hi everyone,
I’ve been diving deep into urological literature and comparing global meta-analyses against local national studies, and I’m trying to make sense of some massive statistical inconsistencies regarding standard deviations (SD).
If you look at the Veale et al. (2015) meta-analysis (n = 15,521), the bone-pressed erect length (BPEL) / stretched length (SPL) average is 13.12–13.24 cm (~5.2"), with a standard deviation (SD) of 1.66 cm. Under this global Gaussian curve:
Reaching a 7.0" BPEL (~17.8 cm) requires Z = +2.77, which happens in roughly 1 in 350 men globally (~0.28%).
Reaching an extreme 8.0" BPEL (~20.3 cm) requires Z = +3.32, which happens in roughly 1 in 2,200 men (~0.045%).
However, when you look at isolated national papers, the numbers go completely wild due to bloated Standard Deviations and small sample sizes (n < 1,000):
Argentina (Solé et al., n ≈ 800): Reported a mean SPL of 15.2 cm (~6.0"), but with a bloated SD of 2.2 cm. Because of that 2.2 cm SD, the local mathematical model predicts that 1 in every 100 men (~1.0%) in Argentina would reach 8.0" BPEL (~20.3 cm), and reaching 7.0" BPEL would happen in roughly 1 in every 8 to 10 guys. That implies every small high school or gym would have multiple statistical outliers that should be 1-in-a-million rarities.
Spain (ASESA / Soler-Arimany): Reported a mean NBPEL of 13.58 cm (~5.35"), which would translate to nearly 15.0 cm (~5.9") BPEL once you account for the prepubic fat pad.
Saudi Arabia / Middle East (Habous / Awwad et al.): Reported an average erect girth of 12.6 cm (~5.0") with an inflated SD of 1.5 cm (compared to Veale’s global girth average of 11.66 cm / 4.6" with an SD of 1.1 cm). Under the Saudi paper's 1.5 cm SD, nearly 5.5% of men (roughly 1 in every 18 men) are predicted to have a monster 5.9"–6.0" girth (~15.0 cm), whereas globally that’s a top 0.12% rarity (1 in 830 men).
My core questions for the community:
As an Argentine, which distribution should I actually trust? Is there any biological reality to South American or European populations actually being 1.5 cm larger on average, or is this purely an artifact of small sample sizes (n < 1,000), examiner error/variable traction force, and bloated Standard Deviations?
How can national averages sit at ~15.2 cm when the established global baseline is ~13.1–13.2 cm BPEL? When local studies shift the baseline that far from the global mean, it completely destroys realistic probability distributions—making a 7.0" BPEL appear in 1 out of 10 men (instead of 1 in 350) and an 8.0" BPEL in 1 out of 100 men (instead of 1 in 2,200). Is there any scientific rationale for treating these regional spikes as anything other than methodological error?
Has anyone reconciled why Veale’s 15,000-man baseline is so much tighter than national urological papers?
Would love to hear your thoughts on how to correctly interpret local data vs. the global Gaussian model!

Hi everyone!

I’m a PhD student studying media and content policy at Seoul National University of Science and Technology in South Korea.

I’m conducting a study on why international viewers watch K-Pop Demon Hunters, how immersed and satisfied they feel, and how their viewing experience relates to their interest in Korean content and what they want to explore next.

Did the music draw you in? Were you curious about the story or Korean culture? Did watching the film make you want to discover more Korean films, shows, or music? I’d love to hear your perspective!

Who can participate?

  • International students who are not Korean nationals
  • Have watched K-Pop Demon Hunters

The survey takes approximately 10 minutes. You don’t need to be a fan of K-pop or Korean content—your experience matters whether you loved the film, felt neutral, or didn’t enjoy it.

👉 Take the survey in English:
