How do you explain quantitative data?
Quantitative data is data expressing a certain quantity, amount or range . Usually, there are measurement units associated with the data, e.g. metres, in the case of the height of a person. It makes sense to set boundary limits to such data, and it is also meaningful to apply arithmetic operations to the data.
What are the different types of quantitative data?
There are two types of quantitative data, which is also referred to as numeric data: continuous and discrete . As a general rule, counts are discrete and measurements are continuous. Discrete data is a count that can’t be made more precise. Typically it involves integers.
