Quantitative data refers to information that can be measured and expressed numerically. This type of data is often collected through surveys, experiments, or observations, allowing researchers to analyze patterns and trends. Examples include measurements like height, weight, temperature, and test scores. This data is typically used in statistical analysis to draw conclusions or make predictions. It can be represented in various forms, such as graphs, charts, or tables, making it easier to interpret. Quantitative data is essential in fields like science, economics, and social research for making informed decisions based on numerical evidence.
