Question

In many journals, when authors report a result such as 16.8±1.4, the 1.4 is the standard error of the statistic and not the margin of error. Rivas et al. (2014) compared the 2D:4D ratio of people with congenital adrenal hyperplasia to a control group. What is the meaning of the value 0.0026 in “0.9806±0.0026”. used by author ? Clearly and concisely state what the value 0.0026 represents. It’s a standard error of some nature, but I don’t want you to use the term “standard error” when describing it

Answer 1

0.0026 is the standard error difference in means of 2D : 40 ratio between people with congenital adrenal hyperplasia and control group. i.e. it is the std. deviation of the sampling distribution of the difference in means of 2D : 4D ratio between ppl with congenital hyperplasia and control.i.e. it is the typical variation around 0.9806 in the 2D: 4D ratio.
