On 22 June 2018, RSS William Guy lecturer, Jeff Ralph, presented a talk on 'Teenagers and society: How statistics reveal the changes in young people’s lives through the last century' at a Year 9 South West Mathematics Masterclass Event taking place at the University of Plymouth. The audience included about 150 pupils from schools across Devon and Cornwall.
Jeff used official statistics to illustrate just how much many aspects of life have changed over the last hundred years. He started by presenting the top five baby names from 2005 for boys and girls and showed how the most popular names have changed since 1900. Using the percentages of boys and girls being born with those top names for the whole population, Jeff produced a good approximation of the number of students in the room with these names, showing that the sample of students in the room provided a good representation of the population as a whole.
