Question

Identify whether the following represent a continuous variable or discrete variable:

(a) Time of a day
(b) Number of words remembered
(c) Income of a person.

Answer 1

Time of a day is a continuous variable, number of words remembered is a discrete variable, and income of a person is a continuous variable.

Step-by-step explanation:

(a) Time of a day: This represents a continuous variable. Time can be measured in fractions of a second, allowing for an infinite number of possible values. For example, the time can be 10:30:15.5, which indicates 10 hours, 30 minutes, 15 seconds, and half a second.

(b) Number of words remembered: This represents a discrete variable. It can only take on whole number values, such as 0, 1, 2, 3, etc.

(c) Income of a person: This represents a continuous variable. Income can take on any value within a certain range, such as $50,000, $75,000, $100,000, etc. It can also be measured in fractions, such as $50,000.50.
