The study involved a random-digit-dialing survey (N = 2,000) of women aged 18-94 years living in the continental United States. Frequency and occurrence of sexual activity decreased with age. Married women in every age group were more likely to have engaged in recent sexual activity. Condom...
We conclude that 2D:4D is negatively related to physical fitness in both men and women. In Study II, there was evidence that the relationship between physical fitness and 2D:4D in men was mediated through an association with exercise frequency. Thus, 2D:4D in males may be a negative ...

A full reproductive history was sought from women, and all participants completed a food frequency questionnaire specifically developed for the MCCS. Physical measurements were also taken, and each participant provided a blood sample. Full details of the MCCS baseline phase are published elsewhere [...

Frequency distribution bar graphs of digit ratios: distribution of digit ratios among daughters (A1 = 2D:4DR, A2 = 2D:4DL), distribution of digit ratios among sons (B1 = 2D:4DR, B2 = 2D:4DL), distribution of digit ratios among mothers (C1 = 2D:4DR, C2 =...
I've been looking at the frequency of the digits of pi in base 2. So far up to the first 400 bits, 0 occurs 57% of the time, 1 occurs 43 % of the time. Running a chi-square test on this gives a result of this being random of only 7%. In other words with this initial samp...
The χ2 test was used to evaluate differences in the frequency of nominal variables. Pearson’s correlations were used to investigate continuous relationships between the 2D:4D measures and GIDYQ and UGDS scores in each group. We present the data as means and standard deviations or relative ...
I have purchased the two PCBs for the 12-Digit Frequency Counter and, after spending some time locating all the parts, I have built it. However there is a problem with the tracks for the ADCH-80 choke on the PCB. You have used pins 3 & 6 but the RFC only has connections to pins...
