Difference Between Discrete And Continuous Variable Math
A continuous variable is uncountable while a discrete variable has countable values.
Difference between discrete and continuous variable math. You can have an elapsed time of 1 0 s or 1 1 s or 1 001 s or 1 0000234 s or 1 000000001 s or any real number. It could be 9 58. We can actually list them. Continuous variable alludes to the a variable which assumes infinite number of different values.
Or the number of accidents at a certain intersection over one year s time possible values are 0. Usually discrete variables are defined as counts but continuous variables are defined as measurements. Discrete variable continuous variable. If the possible outcomes of a random variable can only be described using an interval of real numbers for example all real numbers from zero to ten then the random variable is continuous.
The domain of a discrete variable is at most countable while the domain of a continuous variable consists of all the real values within a specific range. If a random variable takes all possible values between certain given limits it is called as continuous random variable. A discrete variable can only take on certain values. Anyway i ll let you go there.
If a random variable takes only a finite or countable number of values it is called as discrete random variable. Discrete data is countable while continuous data is measurable. It might be 9 56. Discrete random variables typically represent counts for example the number of people who voted yes for a smoking ban out of a random sample of 100 people possible values are 0 1 2.
Values are obtained by counting. So in this case when we round it to the nearest hundredth we can actually list of values. Discrete data contains distinct or separate values. A continuous variable can take on any value at least within a certain range.
It could be 9 57. Values are obtained by measuring. What is the difference between discrete variable and continuous variable. The data set for a discrete variable is finite meaning it has an end value while a continuous variable can take up an infinite value which implies that it can have endless values.
Range of specified number. Continuous data is data that falls in a continuous sequence. For example time is a continuous variable. Continuous random variable.
Hopefully this gives you a sense of the distinction between discrete and continuous random.
