What are discrete variables examples?

A discrete variable is a variable whose value is obtained by counting. Examples: number of students present. number of red marbles in a jar. number of heads when flipping three coins. students' grade level.

What are 5 examples of discrete data?

Which of these is an example of a discrete variable?

The answer is the gender of each student in a psychology class is an example of a discrete variable.

Is age discrete or continuous?

Is Age Discrete or Continuous? Technically speaking, age is a continuous variable because it can take on any value with any number of decimal places.

Is height discrete or continuous?

Height, weight, temperature and length are all examples of continuous data.

Discrete and continuous random variables | Probability and Statistics | Khan Academy

Is eye color discrete or continuous?

Discrete data is organised in separate categories and is often presented in a bar chart. Examples of types of discrete data include: eye colour, hair colour, number of people in a shop, favourite chocolate bar. These values are distinct.

Which variables are always discrete?

Discrete variables are numeric variables that have a countable number of values between any two values. A discrete variable is always numeric. For example, the number of customer complaints or the number of flaws or defects.

Which of the following is NOT example of discrete variable?

Answer and Explanation: The correct answer to the given question is option c) The time spent by a physician with a patient.

Is shoe size discrete or continuous?

1. Shoe size is whole number (discrete), but the underlying measure is foot length which is measurement (continuous) data. Even half sizes are still not really measurement but "whole number", because there is nothing between size 8 and 8 1/2.

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.

Is salary discrete or continuous?

For example, salary levels and performance classifications are discrete variables, whereas height and weight are continuous variables.

What is discrete variable in statistics?

A discrete variable is a variable whose value is obtained by counting. Examples: number of students present. number of red marbles in a jar. number of heads when flipping three coins.

Is temperature continuous or discrete?

Temperature is continuous variable as it does have fractional value too. For example: Today's temperature is 30. 5 degree Celsius, here 30. 5 is not a discrete variable and hence is a continuous variable.

Is hours of TV discrete or continuous?

It depends how did you record the time, e.g. if you count days, or record hours rounded to the nearest hour then it is rather discrete; when you record days, hours and minutes of something happening, then it is closer to continuous.

Is ice cream flavor discrete or continuous?

The ice cream flavor is a categorical variable because the different flavors are categories with no meaningful order.

Is height a continuous variable?

Continuous variables

For instance, consider the height of a student. The height can't take any values. It can't be negative and it can't be higher than three metres. But between 0 and 3, the number of possible values is theoretically infinite.

Is hair color discrete?

Hair colour is a type of discrete data because the values are distinct. You either have one hair colour or another! Continuous data covers a range, so each category is not separate but runs into the next.

Is your weight a discrete variable?

So it is obvious that weight is a continuous variable as it can be quantified with decimal precision;like 10.2 kg and 3.0122 kg.

Is education discrete or continuous?

However, educational attainment is not a discrete variable but a continuous one, and the aggregation into different groups may result in a loss of information, thus introducing a potential source of measurement error.

Is gender a discrete data?

Discrete data: when the variable is restricted to specific defined values. For example, "male" or "female" are categorical discrete data values.

Is heart rate continuous or discrete?

Variables such as heart rate, platelet count and respiration rate are in fact discrete yet are considered continuous because of large number of possible values. Only those variables which can take a small number of values, say, less than 10, are generally considered discrete.

Is speed continuous or discrete?

Yes, speed is a common continuous variable, and the value is chosen by a random process. We know it is continuous because there is always another possible value between any two speed values. It would not be possible to count all of the possible speeds that could be.
