question 6 of 10
bald people who wear diapers tend to cry more often than other people. in this statement, age is a(n):

a. correlation.

b. discrete variable.

c. hidden variable.

d. observation.

Explanation:

In the given statement, bald people wearing diapers and crying more often may be confounded by age (e.g., infants are more likely to be in diapers, cry often, and have less hair/baldness due to age - related factors). A hidden variable (confounding variable) is a variable not considered in the initial statement but influencing the relationship. Option A is incorrect as correlation is a relationship between variables, not a variable type. Option B is wrong as age is typically a continuous variable (not discrete in the context of this confounding role). Option D is incorrect as age is not an observation here but a variable influencing the relationship.

Answer:

C. hidden variable.
