# How do I ask statistics questions on this site?

I recently asked this question after asking this question for two reasons.

1. To get a better idea how drowning works in Call of Cthulhu 7th edition
2. To use the answer to decide how to run my next game. If drowning chance was too high, I would find a way around it, and if drowning chance was too low I would bump up the difficulty.

What I got was mostly people telling me that the probability didn't matter, which didn't help much. I was trying to tune the probability of drowning to have a 1/8 risk of getting drowned by sentient water, to give stakes but not a guaranteed death. But I mostly got no answer which wasn't helping me adjust dice rolls. There were some answers that gave good math and I think accurate rulings, which is enough for me to move forward.

How should I ask questions relating to probability in the future to help people understand the questions?

• I think I posted the wrong question. I asked about the drowning statistic looking to have it come with the chance of death without a guarantee. My goal was not to have dangerous water be completely deadly or safe so I just asked for the number, hoping to tune it.

### When you ask how best to use a hammer to drive a screw, you have to expect some number of people to suggest using a different tool.

You outlined your problem well, and it was clear what sort of answer you were looking for. I've never played the game and I understood the question perfectly well. But one of the neat things about asking questions to a community of experts is that we often see that the best solutions to our problems don't even fit within the framing of our questions. When this happens, we call it a frame challenge:

A frame challenge is where an author answers a question in a wholly different way the querent never asked for, or potentially expressly forbade, but in a way the author feels will actually solve the problem. (Or otherwise improve the querent's life quality or prevent them from making some terrible mistake.)

• I asked how the game's rules work. Instead of being told how the game works I was told how to not use the game's rules. How is that Hammer and Screw?

• @CharlieHershberger You're saying in your question here that you wanted to understand statistics of how likely things are to produce certain results. The answers you're getting here are attempting to suggest that the statistics do not produce those results, and that those results are not a matter of statistics. If you're trying to understand how this part of the game works, the people answering appear to be telling you. Commented Jun 24, 2022 at 23:58
• "I asked how a screw worked with a hammer, and I was told not to use a screw with a hammer." You are wrong about how the game works. Commented Jun 25, 2022 at 0:01
• I think I know what the problem is. People assumed that I wanted characters not to die. That is not the case. I was planning on having between zero and two characters die. I was not asking how to make the water safer, I was asking how to make the water acceptably dangerous. most of the answers completely removed the chance of death, which was not my intention.

• @CharlieHershberger with respect, what you were asking was how deadly the water is when the mechanics of the system are when applied. What you wanted to know was how to make the water acceptably dangerous. These are not the same things, and this disconnect is the source of a lot of questions getting answers that do not satisfy the asker. In general, ask what you really want to know-- you may still have people challenging the frame of your question, but your odds of getting a useful answer go up dramatically.

• One important point: unless you're way off, a good frame challenge will also answer the question actually being asked, at least briefly. If one answer is "You're missing the point" and another is "36%, but you're missing the point", the second should get more votes. Commented Jul 3, 2022 at 5:53
• @SirTechSpec Maybe this falls under “you’re way off”, but one of my highest scoring answers ignores the actual question entirely. Commented Jul 3, 2022 at 7:12

(This is an injoke about some site boilerplate text. Hang around a while, you'll see it eventually if you haven't already.)

One of the functions of the domain knowledge that an expert should possess is to be able to distinguish the meaningful and meaningless elements of the relationships between things in that domain.

This is why the question page asks you to be specific and provide details. If things have come to the point that you hope anonymous strangers on the Internet will be able to solve your problem, you should be honest with yourself that you are, at least situationally, not an expert, and you do not know how meaningful some of the details of your specific situation are -- so provide as many as you can. Be open, be conversational, tell your story! (Well, not the personally identifiable details of your story. This is the Internet, after all.) If some of it turns out not to matter, or to be a distraction from the more relevant elements of your question, you can edit it out later -- regardless of site reputation you can always edit your own stuff freely.

I understand the impulse to pull back into generalities to hope for something useful by chance, but if you need specific help, asking more and more general questions trying to find it is only likely to get you more and more general answers.

Especially in this case, wow! I mean -- you probably already know this, but I'm writing this just as much for a general audience -- Call of Cthulhu has been going for over 40 years now, and over most of that time it's built up something of a reputation as a real investigator meatgrinder. The seventh edition of Call of Cthulhu (CoC7E) is written in what I would, uncharitably, describe as a defensive crouch against its own reputation. "Don't kill the investigators! Don't kill the investigators!" it's screaming, left and right.

Don't kill the investigators... in general.

Where possible try to avoid an outcome that will end the game (unless you wish to, of course).

-- "Failed Dice Rolls and Sudden Endings", CoC7E Keeper Rulebook, p. 86

It's just fine to kill them in specific. Like, when the story's reached its climax and even their deaths would still be interesting.

And hey, while I'm copping to being uncharitable! In what an outside observer would probably call a thoroughly predictable plot element, as this whole affair has dragged on I spent way too much time in close reading of that eldritch tome and it messed with my head a little. I've done jack all to help you get to this point and my responses to your more and more general queries have made the whole thing worse for you.

So: thanks for putting yourself through the process and opening up about what you were trying to do. I'm sorry for the confusion you've been through, both personally induced and in general. If you want to head back to your original question and edit in all these details you've shared - the final confrontation, the dire threat, the desperate escape - I can absolutely get you a better answer.

## You can do so by asking a question only about [statistics]

In earlier editions of Call of Cthulhu, there were none of these modern ideas of failing a skill check not leading directly to failure. In those old editions, when you failed a swim check, you started to drown, period. And if there was no land or boat nearby to drag yourself up to, you would die. It sounds like that is how you want to play, only with skill values that calibrate the probability to a level that you feel is the right one.

In CoC 7e, the probability resolution mechanism still works pretty much in the same way, except for the addition of pushed rolls. But: the rules about resolving statistical probabilities are not the only rules of the game. It does not end there.

The rules about how to deal with the outcome of such rolls are just as much rules of the game, and they they have changed a lot from earlier editions and now loudly and clearly tell you to not let the investigators die if it does not make narrative sense. You prefer to ignore that part of the rules. You prefer to stick with the old-school approach, and let the die fall as they may, consequences be damned.

And you can, but then you are overriding the game's rules. You either can ask a question about probabilities, which is hard to do in a vacuum outside the other game rules, or you can ask a question about how deadly the game rules make swimming. These are very different things.

If you just want a question about a statistical probablity calculation: the way you could ask it is by providing all the assumptions and conditions, as you did with the swimming skill value, and the process that the sequences of rolls are to follow, for a hypothetical homebrew game you are considering. This game may be similar to CoC 7e, but it is not CoC 7e, as it ignores several of the core rules. Then, someone interested can calculate what the probabilities will work out to under the given assumptions and procedure.

However, as soon as you combine this with how this will work in 7e, people will tell you: in a way that makes the statistical rolls really not that important.

• I don't think the advice in the second half of this answer is appropriate. It's attempting to establish territory around the game and assert that nobody can truly ask statistics within that territory. But those rolls and their statistics are a part of the game just as much as the narrative results that may follow, and people should be able to ask questions about them. The answers will also cover the practical aspects of how those stats apply, but that can't mean you can't ask about those stats within the scope of the game. Commented Jun 26, 2022 at 12:46
• @doppelgreener I am trying to answer how he can avoid the issues that he did run into. I do agree you should be able to ask about them, by stating you only are interested in the stats, but he already did that and it did not work Commented Jun 26, 2022 at 12:49
• Divorcing the problem from the game being played is just generally poor advice. We shouldn’t be creating XY problems on purpose, but that’s exactly what you seem to be encouraging here. Commented Jun 26, 2022 at 20:09
• I think it's quite a leap to insist on the ultra-purist stance of forcing someone to state that they're not reeeaaaaally playing whatever game they are clearly actually playing, as the price of minimizing frame challenges. A simple "I am aware of this rule over here, but I'm not asking about that-- I'm asking about this particular rule for this particular reason/aiming for this particular effect," should be enough for most answerers in most situations.
