Quantitative data can be classified into two main types: discrete and continuous. Discrete data is data that can only take on a finite number of values, such as the number of students in a class or the number of times a website is visited.

Quantitative data is often collected using surveys, questionnaires, and experiments. It can also be collected from a variety of other sources, such as government records, financial reports, and social media data.

Once quantitative data has been collected, it can be analyzed using a variety of statistical methods. These methods can be used to describe the data, identify patterns, and test hypotheses. The results of statistical analysis can be used to make decisions, solve problems, and develop new knowledge.
