6 Types of Data in Statistics & Research: Key in Data Science
- Quantitative data. Quantitative data seems to be the easiest to explain.
- Qualitative data. Qualitative data can’t be expressed as a number and can’t be measured.
- Nominal data.
- Ordinal data.
- Discrete data.
- Continuous data.

What are the types of data in research?
Data may be grouped into four main types based on methods for collection: observational, experimental, simulation, and derived.
What is binary type of data?
In statistics, binary data is a statistical data type consisting of categorical data that can take exactly two possible values, such as “A” and “B”, or “heads” and “tails”.Often, binary data is used to represent one of two conceptually opposed values, e.g: the outcome of an experiment (“success” or “failure”)
