- First, let's get a few things out of the way: In real life, we can't put a metal pole between the Earth and the Moon.[1]For one, someone at NASA would probably yell at us. The end of the pole near the Moon would be pulled toward the Moon by the Moon's gravity, and the rest of it would be pulled back.
- Here are a few snapshots of what an actual robot apocalypse might look like: In labs everywhere, experimental robots would leap up from lab benches in a murderous rage, locate the door, and—with a tremendous crash—plow into it and fall over.

- Explain xkcd normal distribution. Pedant: etymologically, there *is* actually a connection between a normal (to a surface or line) and the normal distribution; the former comes from the Latin for a set square (giving you perpendicular), and it later came to mean standard
- P-values are a staple of introductory statistics courses, and are commonly used in the scientific literature to decide whether an effect is significant: if a drug improves survival rates more than could be explained by chance alone, for example. But P-values and significance tests are also easily abused, in more ways than we have time to get.
- This xkcd comic (Frequentists vs which makes it highly unsuitable for frequentist methodology that interprets probability as estimate of how frequent an event is giving that we can repeat the experiment many times. In contrast, bayesian probability is interpreted as our degree of belief giving all available prior knowledge, making it.

3 Answers3. Humor is a very personal thing - some people will find it amusing, but it may not be funny to everyone - and attempts to explain what makes something funny often fail to convey the funny, even if they explain the underlying point.

xkcd, sometimes styled XKCD, is a webcomic created in 2005 by American author Randall Munroe. The comic's tagline describes it as a webcomic of romance, sarcasm, math, and language.

There was a recent effort to quantify whether or not these topics agree with topics derived from the xkcd text corpus using Latent Dirichlet Allocation (LDA). That analysis makes the all too common folly of choosing an arbitrary number of topics

Causation or Correlation: Explaining Hill Criteria using xkcd. This is an attempt to explain Hill's criteria using xkcd comics, both because it seemed fun, and also to motivate causal inference instructures to have some variety in which xkcd comic they include in lectures. By Lucy D'Agostino McGowan, Vanderbilt University A more subtle concept; what's the probability of one event given that another has occurred? The probability of event A given that Bhas occurred is the conditional probability of Agiven B, denoted P[AjB].

By the way, I don't dispute your solution, which is typical of strangeness in Analysis. I just want to assert that there is a difference between an arbitrary real number, which mathematicians take all the time (let x be a real number) and an evenly distributed random real number, which is, as you state, impossible (the distribution would have to be 0 everywhere but have an integral from.

- Therefore, the probability of your daughter reaching a height of 170 cm or more is the integral from 170 to positive infinity over the normal distribution with those parameters.

The probability part could be made into an actual math argument, hypothetically; we could try looking up all the times people reasoned 'thing x worked in past so it will work in future' and it did or did not work out for them and come up with a ratio, for instance, although frankly it's not clear this ratio would actually be useful in any way. Explain for someone who knows nothing about statistics why the researchers would conduct a null hypothesis test. 2. Practice: Use Table 13.1 to decide whether each of the following results is statistically significant. 1. The correlation between two variables is r = −.78 based on a sample size of 137. 2 There are a few obvious ones: one is based Fields Medal caliber math and the other on elementary mistakes in probability; one is studied at an Institute and the other at an Institute. But arguably, neither theory has yet made a clear prediction or explained what it sets out to in a non-circular way

Under Mr. Petzall's plan, the number of deaths would increase to 2.8. This randomized culling would obviously be a big deal—it would be responsible for over a third of all deaths—but, at least for a while, our population would continue to.

Equivalently, the probability of either Case 1 or Case 3 happening is 50%, and the probability of either case 2 or Case 4 happening is 50%. Our goal is to make the probability of either Case 1 or Case 2 (the cases in which we guess correctly) happening greater than 50% While the xkcd cartoon in the chapter's opening figure ends with a rather sinister intepretation of the multiple testing problem as in Figure 6.14), then we can compute the probability that a hypothesis that we reject at this cutoff is a false positive, as follows

The question is: what does almost mean. You can build a confidence interval at the 20%, 10%, 5% level. The most commonly used is the 5% level. A confidence interval at the 5% level means: there is a 95% chance that the true correlation lies in that interval, and a 5% chance that it does not. A 5% chance is 1 chance over 20 Yes it is possible by using and increasing function (such as is greater than 0 step function etc) as a conditions.
