I have been studying statistics for a while now, having watched numerous videos, so I thought maybe it’s time to write my own blog post on the subject.
What is data?
Data refers to facts and statistics collected together for reference or analysis.
Categories of data
The two main categories of data are:-
- Qualitative is composed of nominal and ordinal.
- Quantitative is composed of discrete and continuous.
Qualitative data is composed of:-
- Nominal data is data with no inherent order or ranking, such as gender or race.
- Ordinal data is data with an ordered series.
Quantitative data is composed of:-
- Discrete data is also known as categorical data, it can hold a finite number of possible values. An example is the number of students in a class.
