Quantitative Data Numerical data. Quantitative variables can be continuous or discrete. Continuous : the variable can, in theory, be any value within a certain range.

Can be measured. Examples: height, weight, blood pressure, cholesterol. Discrete : the variable can only have certain values, usually whole numbers. Can be counted. Examples: number of visits to doctor in last year, number of fractures, number of children.

How to Analyze Quantitative Data. Qualitative Data Non-numerical data. Qualitative variables can be nominal or ordinal. Nominal : the variable does not have a specific order. Examples: eye color, blood type, ethnicity. Ordinal : the variable has a specific order. Examples: stages of cancer, class letter grade, position in a race. How to Analyze Qualitative Data.

Data Types in Statistics

Data types are an important aspect of statistical analysis, which needs to be understood to correctly apply statistical methods to your data. There are 2 main types of data, namely; categorical data and numerical data. As an individual who works with categorical data and numerical data, it is important to properly understand the difference and similarities between the two data types. This will make it easy for you to correctly collect, use, and analyze them. The importance of understanding the different data types in statistics cannot be overemphasized.
