What does categorical data mean and quantitative data mean?
& Quantitative data (metric or continuous) is often referred to as the measurable data. This type of data allows statisticians to perform various arithmetic operations, such as addition and multiplication, to find parameters of a population like mean or variance. The observations represent counts or measurements, and thus all values are numerical. Each observation represents a characteristic of the individuals in a population or a sample.
& Categorical data, also called qualitative or nominal, result from placing individuals into groups or categories. The values of a categorical variable are labels for the categories.
