Is it true that a nominal variable is expressed in numbers?

At a nominal level, each response or observation fits only into one category. Nominal data can be expressed in words or in numbers. But even if there are numerical labels for your data, you can’t order the labels in a meaningful way or perform arithmetic operations with them.

How do you tell if a variable is qualitative or quantitative?

Quantitative Variables – Variables whose values result from counting or measuring something. Qualitative Variables – Variables that are not measurement variables. Their values do not result from measuring or counting. Designator – Values that are used to identify individuals in a table.

Is grade continuous or discrete?

Discrete data is data for which all values on the real number line are not possible – only certain values are possible. For example, the grade you receive in your school exam (A, B, C, D, or E) is an example of discrete data because your grade can only take on one of these 5 possible values and nothing else.

Is time a discrete or continuous variable?

Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person’s age in years.

What is the difference between a discrete and continuous variable?

A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A discrete random variable X has a countable number of possible values. Example: Let X represent the sum of two dice.

What is the similarities and differences between continuous and discrete variable?

Discrete variables are the variables, wherein the values can be obtained by counting. On the other hand, Continuous variables are the random variables that measure something. Discrete variable assumes independent values whereas continuous variable assumes any value in a given range or continuum.

Is profit a discrete or continuous variable?

The number of each type of job completed by a company each month, the number of employees required for work each day or the profit a business makes each month are all examples of discrete data.
