Answer:
Explained below.
Step-by-step explanation:
Categorical variables are those variables that represents certain characteristic or attribute. Such as gender, eye color, age limit and so on.
Numerical variables are variables that assumes numerical values. Such as height, weight, time and so on.
Numerical variables are of two types: Discrete and Continuous.
Discrete variables are those variables that assumes finite whole number values. Such as number of girls in a house, number of children in the nursery and so on.
Continuous variables are those variables that assumes values from a fixed interval. Such as length of screw, amount of payment for donations and so on.
The attributes are classified as follows:
a. Brand of computer purchased by a customer : Categorical
b. State of birth for someone born in the United States : Categorical
c. Price of a textbook : Numerical and Discrete
d. Concentration of a contaminant (micrograms per cubic centimeter) in a water sample : Numerical and Continuous
e. Zip code : Numerical and Discrete
f. Actual weight of coffee in a 1-pound can: Numerical and Continuous
