Is this variable discrete or continuous?
A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring.
What are examples of discrete variables and continuous variables?
Difference between Discrete and Continuous Variable
| Discrete Variable | Continuous Variable |
|---|---|
| Examples: Number of planets around the Sun Number of students in a class | Examples: Number of stars in the space Height or weight of the students in a particular class |
Is hair a discrete variable?
Since hairs are something we can count, this is a discrete random variable. Even though the number of hairs may be very large, that we wouldn’t actually want to count them, there are no “half hairs” or fractional amounts of hair, only whole number amounts of hairs.
Is volume of blood discrete or continuous?
Let x represent the volume of blood drawn for a blood test. Continuous, because x is a random variable that cannot be counted. Decide whether the random variable x is discrete or continuous. x represents the number of motorcycle accidents in one year in California.
What is an example of a continuous variable?
A variable is said to be continuous if it can assume an infinite number of real values within a given interval. For instance, consider the height of a student. The height can’t take any values. The age is another example of a continuous variable that is typically rounded down.
Which variable is continuous?
Continuous variables are numeric variables that have an infinite number of values between any two values. A continuous variable can be numeric or date/time. For example, the length of a part or the date and time a payment is received.
Which are continuous variables?
Continuous variables can take on an unlimited number of values between the lowest and highest points of measurement. Continuous variables include such things as speed and distance. Gender or rank are examples of discrete variables because there are a limited number of mutually exclusive options.
What are examples of continuous variables?
You often measure a continuous variable on a scale. For example, when you measure height, weight, and temperature, you have continuous data. With continuous variables, you can calculate and assess the mean, median, standard deviation, or variance.
Is hair color continuous or discrete?
And clearly hair color, skin color and eye color all fall under the definition of a continuous trait, because even though they dont seem to be affected by the environment, they are definitely polygenic traits and show a gradation, so they’re definitely continuous traits.
Is shoe size continuous or discrete?
Discrete data is numerical data that can only take certain values. The number of people on a fair ground ride, the score on a pair of dice, or a shoe size are all examples of discrete data. Continuous data is numerical data that can take any value within a given range.
What is an example of a discrete variable?
Discrete variables are countable in a finite amount of time. For example, you can count the change in your pocket. You can count the money in your bank account. You could also count the amount of money in everyone’s bank accounts.
What is discrete data example?
Discrete data is information that we collect that can be counted and that only has a certain number of values. Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit.
