"When, among a set of observations, any single observation is a word, or a sentence, or a description, or a code that represents a category then the data are qualitative."
"When, among a set of observations, any single observation is a number that represents an amount or a count, then the data are quantitative."
Discrete variable
Discrete variables are numeric variables that have a countable number of values between any two values. A discrete variable is always numeric. For example, the number of customer complaints or the number of flaws or defects.
Continuous variable
Continuous variables are numeric variables that have an infinite number of values between any two values. A continuous variable can be numeric or date/time. For example, the length of a part or the date and time a payment is received
