A stratified sample would ensure that the survey includes women of different ages, while also controlling for other potentially important factors such as occupation or geographic location. Longitudinal data would not be necessary for a one-time survey, interviews with union and non-union employees would not necessarily ensure representation of women of different ages, a sample based on high school placement records would not be representative of all employed women, and a pure random sample may not necessarily include enough individuals from each age group to ensure a representative sample. A stratified sample would ensure that the survey includes women of different ages and would provide a representative sample of all employed women in society by dividing the population into strata (age groups) and randomly selecting participants from each stratum. Longitudinal data refers to collecting data over a period of time and would not necessarily address the issue of age diversity in the survey. Interviews with union and non-union employees would not necessarily address age diversity either. A sample based on high school placement records would not be representative of all employed women in the society. A pure random sample could potentially miss certain age groups and may not provide a representative sample.
