Is the variable is discrete or continuous the number of keys on each student's key chain?
A random variable such as the number of keys on each student's key chain is discrete because you can list the possible values it can assume. If it was continuous one would not be list a continuous random variable because it would be impossible. The keys on the key chains would be discrete.

Is number of students continuous or discrete?
The number of students is discrete. There is no number of students between 4 and 5.
Is the number of pills in a container of vitamins discrete or continuous?
Discrete random variable
Is nationality a discrete or continuous variable?
Neither, since it is "qualitative data", not "quantitative". Only quantitative data can be discrete or continuous. (Unless your assigning a numerical "value" to each nationality type, in which case it would be quantitative discrete). Answer 2: If considering the percentage, eg 100% Irish, 50% Irish, etc., then it is theoretically a continuous variable, assuming an infinite number of generations. However, in terms of currently existing and past living people, for any nationality, it is a discrete variable.

Difference between discrete and continuous?
A continuous variable is one that can take any value within an interval (or a set of intervals). A discrete variable is one that can only take certain values.Some further notes:* Often a discrete variable takes integer values, but that is not necessary.* Neither discrete nor continuous variables need be limited to a finite number of possible values.* Frequently, continuous variables are continuous only in principle, and the measuring instruments or recording make them discrete. Eg your height is continuous but as soon as it is recorded as 1.75 cm or 5'9", it is made discrete.
Number of notes in a song is discrete variable?
number of notes in a song is discrete variables or continuous variables
Is no of common colds a discrete or continuous variable?
It is a discrete variable, as number of colds experienced by individuals would be one time, two times or so on. So, it is a finite category proving it a discrete variable.
Is the number of employees of a company a discrete quantitative variable?
Yes. You can't have a fraction of an employee. Thus, the range of values is not continuous, thus the variable is discrete.
Is the number of students enrolled in the BIOL 106 semester discrete or continuous random variable?
The number of students enrolled in BIOL 106 is a discrete random variable because it can only take on whole number values (0, 1, 2, etc.). You cannot have a fraction of a student enrolled, making it inherently countable. Discrete variables are characterized by distinct and separate values, which fits the context of student enrollment.
What is a discere variable?
A discrete variable is a type of quantitative variable that can take on a finite or countable number of distinct values. Examples include the number of students in a classroom, the result of a dice roll, or the number of cars in a parking lot. Discrete variables contrast with continuous variables, which can take on any value within a given range. In statistical analysis, discrete variables are often represented by whole numbers.
What is the difference between discrete and cumulative distributions?
A discrete distribution is one in which the random variable can take only a limited number of values. A cumulative distribution, which can be discrete of continuous, is the sum (if discrete) or integral (if continuous) of the probabilities of all events for which the random variable is less than or equal to the given value.
