Categorical Variables


  • These are variables that fall into a category
  • There is no order for categorical variables
  • They are not quantitative variables
Ex

1)  HAIR COLOR
Hair color is the category
The variables inside a category are these variables
    • Black
    • Red
    • Blonde
    • Brown
2) GENDER
    • Male
    • Female
    • Trans
ORDINAL VARIABLES
  • These might look like categorical variables. However as they can be ordered they cannot be a categorical variables
       Ex:
       HOUSE PRICES
    • low
    • moderate
    • high
QUANTITATIVE VARIABLES     
  • We can perform mathematical function on these variables
      Ex:
    • 1
    • 2
    • 3
        We can do 1+2+3 =6
