Question

Classify each of the following attributes as either categorical or numerical. For those that are numerical, determine whether they are discrete or continuous. (a) Brand of computer purchased by a customer. categorical numerical (discrete) numerical (continuous) (b) State of birth for someone born in the United States. categorical numerical (discrete) numerical (continuous) (c) Price of a textbook. categorical numerical (discrete) numerical (continuous) (d) Concentration of a contaminant (micrograms per cubic centimeter) in a water sample. categorical numerical (discrete) numerical (continuous) (e) Zip code. (Think carefully about this one.) categorical numerical (discrete) numerical (continuous) (f) Actual weight of coffee in a 1 lb can. categorical numerical (discrete)

Answer 1

(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 discrete

(d) Concentration of a contaminant (micrograms per cubic centimeter) in a water sample - numerical continuous

(e) Zip code - categorical

(f) Actual weight of coffee in a 1 lb can - numerical continuous

Answer 2

Categorical and Numerical(discrete and continuous)

Explanation:

We are given the following information in the question:

We have to classify the given data into categorical or numerical(discrete and continuous)

a) Brand of computer

This will contain data like Intel, Apple, Dell and so on.

Hence, it is categorical.

b) State of birth

This will contain data like California, LA and so on.

Hence , the data is categorical.

c) Price of textbook

Since price is a continuous quantity, the data is continuous numerical.

d) Concentration of containment

Since concentration can be expressed in decimal numbers the data is continuous numerical.

e) ZIP Code

These are 5 digits code and hence always have discrete values.

This is discrete numerical data.

f) Weight of coffee

Since weight is a continuous quantity. it is continuous numerical data.
