Samples are small portions or examples taken from a larger group or population. They are often used in research, testing, or analysis to represent the whole. For instance, in a scientific study, a sample might consist of a few individuals selected from a larger population to draw conclusions about that group. In various fields, such as marketing or quality control, samples help assess characteristics or preferences without needing to examine every item. For example, a company might survey a sample of customers to understand their opinions on a new product, allowing them to make informed decisions based on the feedback received.
