Is age group a continuous variable?
Age can be considered as a continuous, ratio variable..
How do you know if something is discrete or continuous?
Definition: A set of data is said to be continuous if the values belonging to the set can take on ANY value within a finite or infinite interval. Definition: A set of data is said to be discrete if the values belonging to the set are distinct and separate (unconnected values).
Is temperature a discrete or continuous variable?
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. It has wide range and its value is true for all real numbers.
Is year in school nominal or ordinal?
Values of ordinal variables have a meaningful order to them. For example, education level (with possible values of high school, undergraduate degree, and graduate degree) would be an ordinal variable.
Is salary continuous or discrete?
Strictly speaking, it is a discrete variable, given that there is a basic unit of 1p below which measurements cannot be taken. However, 1p is so small in relation to an annual salary (even the annual salary of a teacher) that in practice it is treated like a continuous variable.
Is height a discrete variable?
A discrete variable is one that cannot take on all values within the limits of the variable. … A variable such as a person’s height can take on any value. Variables that can take on any value and therefore are not discrete are called continuous.
What is the similarities of continuous and discrete variable?
The simplest similarity that a discrete variable shares with a continuous variable is that both are variables meaning they have a changing value. Besides that, they are also statistical terminologies used for comparative analysis.
What are examples of discrete and continuous variables?
For example, you could be: 25 years, 10 months, 2 days, 5 hours, 4 seconds, 4 milliseconds, 8 nanoseconds, 99 picosends…and so on. Time is a continuous variable. You could turn age into a discrete variable and then you could count it.
Is smoking status ordinal or nominal?
also a smoking variable, is also constructed on an ordinal scale: Notice how the range between each point is not equal.
Is time in minutes continuous or discrete?
Explanation: Time is a continuous variable, it can take any positive value in an interval. Even when we measure it in minutes, it can be measured with infinite precision, for example: 0.125 minutes or 0.13333 minutes.
What is the difference between discrete and continuous in stats?
A discrete distribution is one in which the data can only take on certain values, for example integers. A continuous distribution is one in which data can take on any value within a specified range (which may be infinite).
Is gender nominal or ordinal?
There are two types of categorical variable, nominal and ordinal. A nominal variable has no intrinsic ordering to its categories. For example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories. An ordinal variable has a clear ordering.
Is gender continuous or discrete?
continuous data. Discrete data: when the variable is restricted to specific defined values. For example, “male” or “female” are categorical discrete data values.
What are the examples of discrete random variable?
Every probability pi is a number between 0 and 1, and the sum of all the probabilities is equal to 1. Examples of discrete random variables include: The number of eggs that a hen lays in a given day (it can’t be 2.3) The number of people going to a given soccer match.
What is an example of a continuous variable?
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.
Is grade discrete or continuous?
Ordinal (ordered) variables, e.g., grade levels, income levels, school grades. Discrete interval variables with only a few values, e.g., number of times married. Continuous variables grouped into small number of categories, e.g., income grouped into subsets, blood pressure levels (normal, high-normal etc)
Is GPA nominal or ordinal?
Is GPA a nominal or ordinal? GPA is an interval measurement; subtraction can be used and distances would make sense. For instance, the distance from 2.3-2.4 is the same distance as 3.7-3.8.
