As a general rule, if you can apply some kind of math (like addition), it’s not qualitative — instead, it’s aquantitative variable. For example, you can’t add blue + green (unless you’re in an art class — even then you “mix” them, you don’t add them!) — making “...
In this chapter, we will mainly deal with how comparative analyses can be reported. This is with the aim to understand when and how a difference may or may not have clinical meaning, beyond the common and inadequate concept, of statistical significance.Cucchetti, Alessandro...
What are Categorical Variables and Statistics for Categorical Variables? Categorical Variables:A categorical variable is a variable that can be broken into categories. This type of variable usually takes on fixed values that can be labeled. For example hair color or breed of cat. You may also hea...

in the ordinal section above, you would also obtain a nonsensical result. Because the spacing between the four levels of educational experience is very uneven, the meaning of this average would be very questionable. In short, an average requires a variable to be interval. Sometimes you have ...
variable, but we would say that it is an ordinal variable. However, in order to be able to use statistics that assume the variable is interval, we will assume that the intervals are equally spaced. Does it matter if my dependent variable is normally distributed?
This survey investigates current techniques for representing qualitative data for use as input to neural networks. Techniques for using qualitative data in neural networks are well known. However, researchers continue to discover new variations or entire

In the case of a classifi- cation problem, ck belongs to the set of possible classes for the target variable. However, in a dirty dataset, as with spelling mistakes, some categories can appear only once, undermining the meaning of their marginal link to y. Clustering. To tackle the ...
