A discrete variable might take on values in sets like these:
'Discrete' here really means 'separate'.
A discrete value is a distinct or separate value that can be counted or categorized, often represented by whole numbers. Unlike continuous values, which can take on any value within a range, discrete values have specific, finite possibilities, such as the number of students in a classroom or the outcome of rolling a die. They are commonly used in statistical analyses and data representation where individual items or counts are relevant.
Discrete variables have numbers that can be counted. Continuous data is measurable. Discrete data are data which can only take on a finite or countable number of values within a given range. Continuous data are data which can take on any value. It is measured rather than counted. The mass of a given sample of iron is continuous; the number of marbles in a bag is discrete.
Two inches of precipitation is considered continuous data. This is because precipitation can take on any value within a range and can be measured with varying degrees of precision, such as in millimeters or hundredths of an inch. Discrete data, on the other hand, consists of distinct, separate values, typically counted items. Since precipitation can vary continuously, it falls into the continuous data category.
Yes.
The number of people in a restaurant with a capacity of 250 is discrete because it can only take on whole number values (e.g., 0, 1, 2, ..., up to 250). You cannot have a fraction of a person, which distinguishes discrete data from continuous data, where values can take on any number within a range.
Any kind of graph can be used for discrete data.

The number of cows in a pasture is a discrete quantity because it can only take on whole number values (e.g., 0, 1, 2, 3, etc.). You can't have a fraction of a cow in this context. Discrete data is characterized by distinct, separate values, while continuous data involves measurements that can take on any value within a range.
Discrete - Each recorded data has a particular whole value e.g. Number of pencils in pencil cases, Number of correct answers in a test Continuous - The recorded data can have any value in a given range e.g. Height of students, Time taken to run 100m

A simple continuous distribution can take any value between two other values whereas a discrete distribution cannot.
In maths there is discrete data and continuous data. Continuous data can be measured to any degree of accuracy, e.g. I am 1.8716749873651 metres tall. Discrete data cannot...e.g. I have 2 sisters. Discrete data cannot have halves or decimals, whole numbers only.
Yes.

You cannot have a fraction of a person, which distinguishes discrete data from continuous data, where values can take on any number within a range.
Continuous data is data that can theoretically be any amount at all. There may be a maximum and minimum value, but all numbers in between are possible. For instance, the amount of time it takes to complete a task, might be 13.4864 seconds. This makes the time continuous data. Discrete is data that can only be set amounts. For instance, how much money someone has, or how many times they've been to the cinema. You cannot have 13.4864 cents, or have visited the cinema 7.33 times. This is a discrete value.
Data that includes only numbers is referred to as quantitative data. This type of data can be further classified into discrete data, which consists of countable values, and continuous data, which can take any value within a given range. Examples include measurements like height, weight, and temperature. Quantitative data is often used for statistical analysis and mathematical computations.
The type of data that contains numbers and exact units is known as quantitative data. This data is measurable and can be expressed in numerical terms, allowing for meaningful mathematical operations. Quantitative data can be further divided into discrete data, which involves whole numbers, and continuous data, which can take on any value within a given range. Examples include height, weight, temperature, and distance.
