Question

Are you a girl or a boy is an example of $.........$ variable.
$\left( a \right){\text{ continuous}}$
$\left( b \right){\text{ dependent}}$
$\left( c \right){\text{ discrete}}$
$\left( d \right){\text{ nominal}}$

Answer 1

Hint:
The statement is in the answerable form, or we can say the statement that can be answered like, in numbers, yes or no, either or this, etc. are called variables which are discrete and with this, we can now easily answer this question.

Complete step by step solution:
A discrete variable is a variable whose value is obtained by counting like, number of heads or tails when flipping n coins at a time or how many got 90percentile marks in the exam, or the number of boys in the class.
Hence, are you a girl or a boy is an example of a discrete variable.

Therefore, the option $\left( c \right)$ is correct.

Additional information:
A continuous variable is a variable whose value is obtained by measuring. For example- age, height, etc.
A nominal variable that has at least two classes. Here in this non-numeric name or numeric code will be utilized. For example- students of a college are arranged by the school in which they are selected utilizing a non-numeric name, for example, Business, Humanities, Education, etc.
Similarly, a dependent variable is a variable that is tested or being experimented with. For example- a test mark that is being measured from $0$ to $100$ . It is just that, a variable that is subject to an autonomous variable(s). For instance, for our situation, the test mark that an understudy accomplishes is reliant on update time and insight. While amendment time and insight (the free factors) may (or may not) cause an adjustment in the test mark.

Note:
As from the above a point should be noted that the discrete variables are countable and are justifying the statements. So we can say that it will be countable for a finite amount of time. For example- the counting of planets. We can easily count it so it will come under a discrete variable.
