==Explanation==
This comic plays on how scientific experiments interpret the significance of their data. {{w|P-value}} is a statistical measure indicating, roughly, how likely that the results could have happened by accident. Conventionally, analyses with a ''p''-value less than .05 (i.e. above 95% that it isn't due to chance) are said to be 'statistically significant'. Although the difference between .04 and .06 may seem minor, the practical consequences can be major. For example, scientific journals are much more likely to publish statistically significant results. In medical research, billions of dollars of sales may ride on whether a drug shows statistically significant benefits or not. A result which does not show the proper significance can ruin months or years of work, and might inspire desperate attempts to 'encourage' the desired outcome.

When performing a comparison (for example, seeing whether listening to various types of music can influence test scores), a properly designed experiment includes an ''experimental group'' (of people who listen to music while taking tests) and a ''control group'' (of people who take tests without listening to music), as well as a ''{{w|null hypothesis}}'' that "music has no effect on test scores". The test scores of each group are gathered, and a series of statistical tests are performed to produce the ''p''-value. In a nutshell, this is the probability that any observed difference in scores between the experimental and control group could occur due to random chance, rather than the actual experimental stimuli. For a more drastic example, an experiment could test whether wearing glasses affects the outcome of coin flips - there would likely be some amount of difference between the coin results when wearing glasses and not wearing glasses, and the ''p''-value serves to essentially test whether this difference is small enough to be attributed to random chance, or whether it can be said that wearing glasses actually had a significant difference on the results.

If the ''p''-value is low, then the null hypothesis is said to be ''rejected'', and it can be fairly said that, in this case, music does have a significant effect on test scores. Otherwise if the ''p''-value is too high, the data is said to ''fail to reject'' the null hypothesis, meaning that it is not necessarily counter-evidence, but rather more results are needed. The standard and generally accepted ''p''-value for experiments is <0.05, hence why all values below that number in the comic are marked "significant" at the least.

The chart labels a ''p''-value of exactly 0.050 as "Oh crap. Redo calculations" because the ''p''-value is very close to being considered significant, but isn't. The desperate researcher might be able to redo the calculations in order to nudge the result under 0.050. For example, problems can often have a number of slightly different and equally plausible methods of analysis, so by arbitrarily choosing one it can be easy to tweak the ''p''-value. This could also be achieved if an error is found in the calculations or data set, or by erasing certain unwelcome data points. While correcting errors is usually valid, correcting only the errors that lead to unwelcome results is not. Plausible justifications can also be found for deleting certain data points, though again, only doing this to the unwelcome ones is invalid. All of these effectively introduce sampling bias into the reports.

Values between 0.051 and 0.06 are labelled as being "on the edge of significance". This illustrates the regular use of "creative language" to qualify significance in reports, as a flat "not significant" result may look 'bad'. The validity of such use is of course a contested topic, with debates centering on whether ''p''-values slightly larger than the significance level should be noted as nearly significant or flatly classed as not-significant. The logic of having such an absolute cutoff point for significance may be questioned.

Values between 0.07 and 0.099 continue the trend of using qualifying language, calling the results "suggestive" or "relevant". This category also illustrates the 'technique' of resorting to adjusting the significance threshold. Appropriate {{w|Design of experiments|experimental design}} requires that the significance threshold be set prior to the experiment, not allowing changes afterward in order to "get a better experiment report", as this would again insert bias into the result. A simple change of the threshold (e.g. from 0.05 to 0.1) can change an experiment's result from "not significant" to "significant". Although the statement "significant at the ''p''<0.10 level" is technically true, it would be highly frowned upon to use in an actual report.

Values higher than 0.1 are usually considered not significant at all, however the comic suggests taking a part of the sample (a ''subgroup'') and analyzing that subgroup without regard to the rest of the sample. Choosing to analyze a subgroup ''in advance for scientifically plausible reasons'' is good practice. For example, a drug to prevent heart attacks is likely to benefit men more than women, since men are more likely to have heart attacks. Choosing to focus on a subgroup after conducting an experiment may also be valid if there is a credible scientific justification - sometimes researchers learn something new from experiments. However, the danger is that it is usually possible to find and pick an arbitrary subgroup that happens to have a better ''p''-value simply due to chance. A researcher reporting results for subgroups that have little scientific basis (the pill only benefits people with black hair, or only people who took it on a Wednesday, etc.) would clearly be "cheating." Even when the subgroup has a plausible scientific justification, skeptics will rightly be suspicious that the researcher might have considered numerous possible subgroups (men, older people, fat people, sedentary people, diabetes suffers, etc.) and only reported the subgroups for which there are statistically significant results. This is an example of the {{w|multiple comparisons problem}}, which is also the topic of comic [[882]].

If the results cannot be normally considered significant, the title text suggests as a last resort to invert p<0.050, making it p>0.050. This leaves the statement mathematically true, but may fool casual readers, as the single-character change may go unnoticed or be dismissed as a typographical error ("no one would claim their results aren't significant, they must mean p<0.050"). Of course, the statement on its face is useless, as it is equivalent to stating that the results are "not significant".

1368: One Of The

2014-07-23T19:00:58Z

199.27.130.222:

{{comic
| number = 1368
| date = May 14, 2014
| title = One Of The
| image = one_of_the.png
| titletext = 'The world's greatest [whatever]' is subjective, but 'One of the world's greatest [whatever]s' is clearly objective. Anyway, that's why I got you this 'one of the world's greatest moms' mug!
}}

==Explanation==

When describing things, reporters try to make only factual statements. If reporters use absolutes (that something is the largest or the smallest thing of its class, or that it is unprecedented, to give several examples) they risk making errors: it is possible that some other example of the thing exists that is even larger or even smaller or that there was some similar incident in the past, and they were not aware of it. If a reader or viewer points out the existence of that thing, even if obscure or trivial, the reporter must issue a correction. As a result, reporters learn to hedge by using formulations such as "one of the biggest" or "a rare example of."

[[Randall]] states that it is his {{W|pet peeve}} when reporters avoid absolutes unnecessarily — that is, in cases where there's vanishingly little risk of error. As an absurd example, Randall depicts one such reporter using this language about the {{w|Gateway Arch}}. As the most well-known monument in Missouri and the largest free-standing arch in the world, it's indisputable that this would be the most recognizable arch in St. Louis.

In the title text, Randall jokes about what could happen if you misunderstand the practice of avoiding absolutes; he thus appears to think it is an ostentatious display of faux objectivity, as opposed to a correction-avoiding strategy. The title text refers to novelty mugs (and t-shirts, and other printed items) that use superlative descriptions such as "World's Greatest Mom" or "World's Greatest Dad." Obviously, such a statement is an expression of personal affection on the part of the family member who gave such a gift and is not meant to be understood as a literally true fact about the world. Using a parody of reporter-speak (like giving a mug to your mother that says "one of the world's greatest moms") would ruin the compliment by suggesting to her that you thought some other people's moms were as good or better.

The title text also refers to {{w|Mother's Day}}, which in the US was three days before this comic was published.

==Trivia==

This comic is referenced in ''What If'' article 89, '''Tungsten Countertop''', with the quote "the sun is one of the meltiest things in the solar system."

727: Trade Expert

2014-07-17T20:01:53Z

199.27.130.222: /* Explanation */

{{comic
| number = 727
| date = April 14, 2010
| title = Trade Expert
| image = trade_expert.png
| titletext = I mean, it's been almost twenty years. Now, it's possible you're simply embedding Windows directory paths in your URIs, but in that case you need more than just a short lecture.
}}

==Explanation==
The {{w|Slash (punctuation)|forward slash}} (/) is the correct way to separate distinct parts of a web address; for example in the address "<nowiki>http://en.wikipedia.org/wiki/Slash_(punctuation)</nowiki>", a forward slash follows the "org" and the "wiki". However, some newscasters are unfamiliar with the distinction between the different types of slashes, thus confusing the forward slash with the {{w|backslash}} (\), the wrong character. They may also be somewhat overzealous by trying to specify forward- or backslash since just saying "slash" would be sufficient.

The title text refers to how in the Windows operating system, the backslash is actually used instead of the forward slash as a separator (in contrast to Unix-based systems, which use the forward slash). Thus, the path to any Windows file encoded in a {{w|Uniform resource identifier|URI (uniform resource identifier)}} would correctly contain the backslash character. However, placing such a URI into a web address to be shared on a news show would be completely useless, as they are only accessible inside of a local {{w|Windows domain}} (usually one's own computer) and no one would be able to access that file over the Internet.

Are there any panels that have two speech bubbles that are not dead ends? It seems that there are never any options for the second bubble, and sometimes the first bubble has options that would fit in the second bubble after the other options for the first bubble. Maybe submissions for the second bubble accidentally end up in the first instead? Another bug? [[User:Zweisteine|Zweisteine]] ([[User talk:Zweisteine|talk]]) 23:56, 2 April 2014 (UTC)

There's a change for us still-bugged people (well, me at least). The "show previous comic" part is gone. It shows a blank area (instead of Comic 1349 and a blank area of the same size) and the page-source shows that the ''<nowiki><img src="http://imgs.xkcd.com/comics/shouldnt_be_hard.png" title="Every choice, no matter how small, begins a new story." alt="Lorenz" /></nowiki>'' part has now been excised from the page. That's on Javascript-enabled, cookie-enabled Firefox ''and'' IE browsers, and every valid URL configuration one can think of (including shift-refreshing to force redownloading, just in case it was page-cache issues as well). I'll update the Bugs section of the explanation page with a summary of that, if you don't mind. [[Special:Contributions/141.101.88.211|141.101.88.211]] 01:48, 4 April 2014 (UTC)

We need some place to discuss certain issues. I give it a shot below [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:10, 2 April 2014 (UTC)
;Transcipt discussion
;Design
*What about four transcripts - one for each of the four first original choices?
*Should these transcripts be on a separate page? It becomes tedious to scroll to the discussion page...[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:13, 2 April 2014 (UTC)
*Could we use the hide option so you only see the options from the first panel. Then you unhide to see the next panel etc. This would be a little like the comic and would make it much easier to read and it would not be such a long page! [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 10:35, 3 April 2014 (UTC)
*:I'm working on the hide option. [[User:Daniel Carrero|Daniel Carrero]] ([[User talk:Daniel Carrero|talk]]) 15:14, 3 April 2014 (UTC)
*::I now implemented the hide option. It looks good! in my opinion. It should be easy to edit. It would be too much work to convert the whole thing to the collapsible version so, sorry but I just removed the whole thing and started from the very beginning. This[http://www.explainxkcd.com/wiki/index.php?title=1350:_Lorenz&oldid=64245] is the link to the old version, in case anyone wants to help converting it to the collapsible version. [[User:Daniel Carrero|Daniel Carrero]] ([[User talk:Daniel Carrero|talk]]) 16:46, 3 April 2014 (UTC)
:I did the same for trivia with a separate page for the old version that can be expanded if anyone wishes. And all the work is not lost. I have linked to it from trivia but it is here: [[1350: Lorenz/Transcript]]. [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 22:19, 4 April 2014 (UTC)
*How will the transcript work for when two characters speak? Those cases do exist; they're not all bugged. For example, in the "OpenBSD Branch", "Why not haiku?" and "Let's go exploring!" have further responses. --[[Special:Contributions/199.27.128.63|199.27.128.63]] 06:31, 5 April 2014 (UTC)
;Characters
*Where does the name Dave come from for the hairy guy who comes in after the first panel? I can see it once in the transcript - but it is said by White hat the sales guy. I'm not sure it is his name and the chatagory for hairy is assigned to the comic! [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:16, 2 April 2014 (UTC)
** Also he is called Dave here: http://www.xkcd.com/1350/#p:3b1a226e-b9c6-11e3-8001-002590d77bdd [[User:Daniel Carrero|Daniel Carrero]] ([[User talk:Daniel Carrero|talk]]) 21:37, 2 April 2014 (UTC)
*Hat guy? Is it a hat? Is there not a better English word for the type of "hat" worn by the main character from the first panel? It is not a hat like white or black hat! [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:18, 2 April 2014 (UTC)
** I named him Hat Guy originally to make things easier. Feel free to change the name, I guess :) Knit Cap Guy, maybe? If a change is warranted, a simple search-and-replace should do it. Also, I'm not sure it's a guy or a girl... But the previous text was also treating him as male to begin with, anyway. [[User:Daniel Carrero|Daniel Carrero]] ([[User talk:Daniel Carrero|talk]]) 21:36, 2 April 2014 (UTC)
*Is the right politician = Cueball?
*Who is the left? [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:23, 2 April 2014 (UTC)

Isn't is likely that the characters only have names given to them by us readers in our suggestions? They don't necessarily have constant names. [[User:Zweisteine|Zweisteine]] ([[User talk:Zweisteine|talk]]) 23:33, 2 April 2014 (UTC)

Exactly my point. I think we should stick with hairy guy and maybe Knit Cap Guy! [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 10:28, 3 April 2014 (UTC)

:I see you already changed Hat Guy to Knit Cap Guy and Dave to Hairy. Knit Cap Guy is a nice name. Originally, I would disagree with you and insist we should stick to Dave because that's what the character is called in one storyline of the strip itself, but I see he is also called Frank in other timeline. Since he has multiple names, using just Hairy is better in my opinion, too. [[User:Daniel Carrero|Daniel Carrero]] ([[User talk:Daniel Carrero|talk]]) 12:40, 3 April 2014 (UTC)

Knit Cap Guy is probably a Girl. Just sayin'. [[Special:Contributions/173.245.52.28|173.245.52.28]] 12:22, 3 April 2014 (UTC)

::Well I think you are correct - that it is a girl. However you can NEVER use text in the comic to decide - because it is user created - I could have written the same line with guy instead of girl!

;Images
I created [[1350: Lorenz/Images]] with all the images I could find in the comic. I'm not sure if I should have left them in the main page [[1350: Lorenz]], but feel free to decide what to do with them.
