Statistics:Different Types of Data/Quantitative and Qualitative Data

Quantitative and qualitative data are two types of data.

[[Qualatative data}}
Qualitative data -- measurement expressed not in terms of numbers, but rather by means of a natural language description. In statistics it is often used interchangably with "categorical" data.

For example: favourite colour = "blue" height = "tall"

Quantitative data
Quantitative data -- measurement expressed not by means of a natural language description, but rather in terms of numbers.

For example: favourite colour = "450 nm" height = "1.8 m"
