Statistical Data

Quantitative : Discrete, Continuous

Referred to as numeric,  Quantitative data have two types: Discrete and Continuos. Continuous are measurement and discrete are counts, as a general rule.

A count that can't be made precise more is discrete data. It involves integers typically. It is a discrete data which is the number of children (or pets, or adults), for instance, the reason is whole are counting by yourself, entities indvisible: 1.3 pets or 2.5 kids, you can't have it.

On the other hand, continuos data, to finer and finer levels it could reduce and could be divided. For examlple, at progressively more precise - beyond, milimiters, centimeters and meters - so height are continuos data.

Qualitative 

Qualitative data is characterizes or approximates by data but properties, attributes, characteristics, etc are not measured,  of phenomenon or a thin. Whereas quantitative data defines is where qualitative data describes.
