A research method in psychology involves analyzing data collected from a population, or a representative subset, at one specific point in time. This approach provides a snapshot of the characteristics and relationships among variables as they exist concurrently. For example, a researcher might administer a survey to different age groups to assess the prevalence of certain attitudes toward technology in the population.
This methodological tool is particularly valuable for its efficiency and cost-effectiveness. It allows researchers to gather preliminary data and identify potential associations between variables without the time and expense required for longitudinal studies. Historically, this methodology has been used to establish prevalence rates of conditions or behaviors within a population, informing public health initiatives and resource allocation strategies.
