162.158.183.211: Clickjacking

Wow, this took me a while to figure out... — [[User:Sqrt-1|The 𝗦𝗾𝗿𝘁-𝟭]] [[User talk:Sqrt-1|talk]] [[Special:Contributions/Sqrt-1|stalk]] 03:48, 23 January 2021 (UTC)

Behold, the most ominous caption of all time. [[Special:Contributions/172.69.34.152|172.69.34.152]] 07:38, 23 January 2021 (UTC)

When I saw this explanation the title text was explained like this:
:Title text is a similar recaptcha thing trying to also do identity fraud at coords 3,3 and 4,3.
What does that even mean? I will change it, but if there is a meaning to those coordinates? then reinsert and explain... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 10:09, 23 January 2021 (UTC)

:I'm guessing 3,3 and 4,3 refer to the table of boxes in the comic itself - the two boxes that contain the malware window are in the third row counting down from top, counting from the left one is in the third box and one in the fourth left box. Not particularly relevant to the title text, though. [[Special:Contributions/172.68.146.216|172.68.146.216]] 13:50, 23 January 2021 (UTC)

Not all 9-tuples of digits can be determined from their pairs of digits. For example, 123-45-6781 and 234-56-7812 have the same pairs. Likewise, 121-31-4151 and 121-41-5131 have the same pairs [[Special:Contributions/162.158.62.157|162.158.62.157]] 13:23, 23 January 2021 (UTC)
:This makes me wonder what the smallest difference n-m is so that you cannot uniquely determine an n-tuple of numbers from all m-tuples contained within it. [[Special:Contributions/162.158.158.253|162.158.158.253]] 20:24, 23 January 2021 (UTC)

This is called a [[wp:Clickjacking|Clickjacking]] attack, isn't it?--[[Special:Contributions/162.158.183.211|162.158.183.211]] 01:45, 24 January 2021 (UTC)

==Explanation==
{{incomplete|Created by a PLACEBO GROUP. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

This comic is another comic in a [[:Category:COVID-19|series of comics]] related to the {{w|2019–20 coronavirus outbreak|2020 pandemic}} of the {{w|coronavirus}} {{w|SARS-CoV-2}}, which causes {{w|COVID-19}}.

The main focus of the comic is a graph showing cases of COVID-19 versus time for two groups: one group was vaccinated and the other group was not. Graphs are ways to visualize data, and almost always indicate specific values. This graph does not; it simply has two lines, and no indication of any of the scale values involved. The higher line ("placebo group") rises in a steep curve. The lower line ("vaccine group") follows the first for a bit but then levels out to a much slower rate of climb. The caption eschews statistical analysis in favor of a holistic assessment: the vaccine is clearly working; just look how much those lines diverge.

This comic was released one day after the [https://www.fda.gov/media/144434/download FDA's Dec 17th briefing document] for the {{w|mRNA-1273|Moderna COVID-19 vaccine}} was released. The document includes the following [https://www.zq1.de/~bernhard/images/share/mRNA-1273-trial.png chart]: [[File:FDA_Modena_Dec17.png]]. The charts draw the integral of the incidence data rather than the data itself ("cumulative" rather than "rate"): this results in changes in disease rate towards the left side of the chart, being added into the data on the right side, amplifying their difference. This technique for emphasizing the data is valid: the spread between the lines only continues to increase if the effect continues happening, such that the total spread at the right is proportional to the total effect the vaccine had. The charts do not show any information on other possible variables. Randall has described previously in his webcomics how very clear charts can be made to hide misleading data. The linked graph does not leave the numbers out, and the numbers indicate the vaccine is 91% effective at preventing the disease (and a 95% chance of being between 85 and 95% efficient).

The advice here could be seen as the inverse of the "science tip" in [[2311: Confidence Interval]], in which the data was so ''bad'' that its error bars fell outside of the graph and were not shown.

:[Shown is a graph with the x-axis labeled "time" and the y-axis labeled "COVID cases." There is a black line on the graph labeled "placebo group", which has a roughly linear slope moving toward the top right corner. There is a red line labeled "vaccine group", which follows the black line for about an eighth of the width of the graph before leveling off.]

:Statistics tip: Always try to get data that's good enough that you don't need to do statistics on it
