Sex-role stereotyping - The article "A Cross-Cultural Content Analysis of Sex-Role Stereotyping in Television Advertisements" compares sex-role
stereotyping in British and New Zealand television advertisements. One of the coding or classification procedures involved the Location where the
central figures in the advertisement were depicted. The researchers were interested in determining whether there is an association between Sex of the
central figures and Location where they are depicted in the advertisement. The table below summarize the observed data for Great Britain, consistent
with the article mentioned above.
