In the post, PG states that First Round's study is evidence of gender bias in VC financing. But footnote [2] is important: Uber was excluded as an outlier. Now.

In the post, PG states that First Round's study is evidence of gender bias in VC financing. But footnote [2] is important: Uber was excluded as an outlier. Now...excluding Uber is reasonable (it is sort of an outlier), but so is not excluding it (it was a company that First Round invested in). When the conclusion from a data analysis depends on which way you go on something like this - which of two reasonable alternatives you pick - then the results are fragile and they don't really support either conclusion very well.
