Final answer:
A nonexperimental quantitative study example is an observational study where researchers may conduct surveys to collect numerical data without manipulating the study variables. Case studies and surveys, such as political polls or health assessments, are typical forms of this research approach.
Step-by-step explanation:
An example of a nonexperimental quantitative study is an observational study. For instance, an observational study might involve researchers conducting a survey measuring various characteristics of a population without attempting to manipulate or control the variables. One classic example is examining the nutritional habits of a group of individuals and correlating these habits with health outcomes, such as the prevalence of heart disease. It's essential to note that in these types of studies, the researchers collect numerical data that can be analyzed statistically but do not intervene in the participants' behaviors or environments.
Another example of a nonexperimental quantitative study could be a research project where data about the number of cases of a particular disease within various demographic sectors is collected and analyzed to identify patterns and risk factors. These studies often use questionnaires, polls, or existing statistical data to gather information.
Case studies and surveys, like political polls or health and nutrition assessments, are common forms of nonexperimental quantitative research. They focus on gathering and analyzing numerical data to discover patterns, correlations, or trends within a given population regarding specific variables of interest.
