A form of observational method in which the researcher examines the accumulated documents, or archives, of the culture (i.e., diaries, novels, magazines, newspapers, etc.)
Not observing people in real-time; studying records of those people
E.g., let’s say you want to do a study investigating how the perceived ideal body type for a woman has changed over the years
You could look at the covers of major magazines over the last 40 years and compare the body shapes and weights of the cover models
You could compare the height weight ratio of the winners of the Miss America pageant over the last 40 years
Which type of research design is this ?
