Video - Types of data

Categorical data includes nominal data in which the order does not matter, such as the hair color of a certain population and ordinal data in which the order is important, such as estimating the degree of pain on a scale from one to ten. Numeric data includes interval data, such as the temperature and ratio data, such as the length of a particular group of students. Numeric data can be continuous, i.e., with intermediary values or discrete, i.e., without intermediary values.
