qualitative data

Statistics is the science of collecting, analyzing, presenting, and interpreting data. Data can be quantitative, measuring "how much," or qualitative, providing labels for categories. Qualitative data describes quality or kind.12

In statistics, qualitative variables might include categories like gender or marital status, while quantitative variables measure things like age or income. The field is crucial for turning large amounts of data into useful information across various disciplines, including healthcare, business, and economics. Statistical inference uses sample data to make statements about a larger population, employing methods like estimation and hypothesis testing.1
