arbuthnot: Male and female births in London

Male and female births in London

Description

This data set is for teaching and training purposes. Arbuthnot's data describes male and female christenings (births) for London from 1629-1710. John Arbuthnot (1710) used these time series data to carry out the first known significance test. During every one of the 82 years, there were more male christenings than female christenings. As Arbuthnot wondered, we might also wonder if this could be due to chance, or whether it meant the birth ratio was not actually 1:1.
