Some researches shows gross measures of body strength suggest that females are approximately 50-60% as strong as males in the upper body, and 60-70% as strong in the lower body. [31] One study of muscle strength in the elbows and knees—in 45 and older males and females—found the strength of females to range from 42 to 63% of male strength. [32]
In Olympic weightlifting, male records vary from 5.5× body mass in the lowest weight category to 4.2× in the highest weight category, while female records vary from 4.4× to 3.8×, a weight-adjusted difference of only 10–20%, and an absolute difference of about 30% (i.e., 492 kg vs 348 kg for unlimited weight classes; see Olympic ...
It was found that the group of men slightly outperformed the women in both the verbal-numerical reasoning and reaction time tests. Subsequently, the researchers tested to what extent the differences in performance was mediated by the varying attributes of the male and female brain (e.g. surface area) using two mixed sample groups.

In the absence of a Y chromosome, the fetus will undergo female development. This is because of the presence of the sex-determining region of the Y chromosome, also known as the SRY gene. [5] Thus, male mammals typically have an X and a Y chromosome (XY), while female mammals typically have two X chromosomes (XX).
One line of inquiry has focused on the role that stereotype threat might play in mathematics performance differences between male and female test-takers. [27] Systematic reviews and meta-analyses suggest that stereotype threat is implicated in performance differences on some mathematics tests, though the effect appears to vary considerably in ...

For example, he highlights findings from the Novara Expedition of 1861–1867 where "a vast number of measurements of various parts of the body in different races were made, and the men were found in almost every case to present a greater range of variation than the women" (p. 275). To Darwin, the evidence from the medical community at the time ...
