Attributes and Variables

Attributes and variables are two important concepts in statistics. An attribute is a characteristic or property of an object or an individual. For example, the color of a car, the gender of a person, and the brand of a smartphone are all attributes. A variable, on the other hand, is a quantity or a value that can vary or change. A variable can be measured or observed and can take on different values.

Types of Variables

There are two main types of variables in statistics: discrete variables and continuous variables.

Discrete variables are variables that can only take on certain specific values. These values are usually integers or counts. For example, the number of children in a family, the number of cars in a parking lot, and the number of students in a classroom are all discrete variables.

Continuous variables, on the other hand, are variables that can take on any value within a certain range. These values are usually measured on a scale, such as time, weight, or temperature. For example, the height of a person, the temperature of a room, and the amount of rainfall in a city are all continuous variables.

Marks of a Student

Marks of a student are an example of a discrete variable. This is because marks can only take on certain specific values, such as 50, 60, 70, and so on. Marks cannot take on any value between these specific values, such as 63.5 or 68.9. Therefore, marks are not a continuous variable.

Conclusion

In conclusion, attributes and variables are important concepts in statistics. Marks of a student are an example of a discrete variable, which is a type of variable that can only take on certain specific values.
