Quantitative variables are measured and expressed numerically, have numeric meaning, and can be used in calculations. Categorical variables are those that provide groupings that may have no logical order, or a logical order with inconsistent differences between groups (e.g., the difference between 1st placeand 2 second place in a raceis not equivalent to the difference between 3rd place and 4th place). If X and Y are independent The probability that X is between an interval of numbers is the area under the density curve between the interval endpoints A categorical variable is one who just indicates categories.
