Meta-analyses are intended to account for possible individual error within each study, summarising the general results of all of its studies in order to potentially draw a useful conclusion. |

Accordingly, even page 53,589 of the meta-analysis is only about a quarter of the total graph. Below is an estimate of the average effect (the effect normally being the relationship being analysed by the studies within a meta-analysis, though here it seems again to just be a conglomerate of all known effects), along with a (likely) 95% {{w|confidence interval}} for the findings of the meta-analysis. |
− | + | In the caption, Randall delivers to us the bad news: that the meta-analysis of "all of science" has finally been performed, and as it turns out, the results are not significant. {{w|Statistical significance}} is the degree to which the results of a sample or study are likely due to a correlation, as opposed to chance or {{w|sampling variation}} alone. Apparently, across the entirety of human science in the study of our universe, the study has found a lack of significance, or a relationship between any two variables ever. | |
− | + | The joke lies in the absurdity of the claim, that "all of science" can be analyzed at all. Science is not a singular term that can be subcategorized in such a manner, but hundreds of different fields of study, many of which have little or no overlap. Doing a meta-analysis of geology and philosophy, for example, would be patently ridiculous, so the 53,589 page study is comical in its very existence, much less conclusion. | |
− | + | In the title text, Randall reports that {{w|subgroup analysis}} is ongoing, which in this context could simply be the various fields of scientific study, ranging from {{w|chemistry}} to {{w|physics}} to {{w|astronomy}} and everything beyond. Thus a subgroup analysis from the limited perspective of the meta-analysis would seem rather unnecessary, not to mention that several levels of sub-subgroup analysis may be needed. | |

A horizontal axis centered on 0 is shown at the bottom and -1 and +1 on either side are labeled. In the middle of the plot, there is a dashed vertical line. On both sides of the vertical line in separate rows, there are black boxes of different sizes with horizontal bars of varying lengths on the sides of the boxes. Below the plot, slightly to the right of the vertical line, there is a black diamond wider than it is tall, labeled "0.17 (-0.14, 0.52)".] |
