− | The panel | + | {{incomplete}} |
− | + | The panel satirises the common misunderstanding of the concept of percentage. Quoting a percentage figure, without mentioning the base which this ratio acts on is meaningless (outside of arithmetic for arithmetic's sake). Most everyday communication however, succumbs to such incompleteness. In the aftermath of this ambiguity, people tend to conflate relative and absolute changes. | |

− | [[ | + | If the probability of a shark attack at the North beach is 0.000001 (one in a million), then the probability of shark attack at the South beach is still 0.0000012 (1.2 in a million). The difference between these values is not enough to normally justify choosing one beach over the other. [[Cueball]] parodies the concern by noting that by going a third time their chance of attack by dogs with handguns increases by 50%. If the chance of the dog attack is 0.000000001 (one in a billion) on each visit to the beach, then in after two visits the chance of attack is is about 0.000000002 whereas after three visits it becomes 0.000000003. |
− | + | But this is also just a common misunderstanding on statistics, while they had no attacks at the first two visits the risk on this single trip is also only 0.000000001. The third visit doesn't increase the risk at this trip. | |
− | + | [[Beret Guy]] further misunderstands probability by believing that - since they haven't been attacked in their first two trips, the chance of attack by dogs with handguns is much higher on their third outing. | |
− | The | + | The title text discusses the argument that, if a tiny risk increased by 50% is still tiny, then since any probability can be reached by repeatedly increasing by 50%, then any probability is "tiny". [[Randall]] is about to debate this when he presumably sees a dog with a handgun. |
