A continuous random variable is a variable that can take on any value within a certain range
A continuous random variable is a variable that can take on any value within a certain range. Unlike discrete random variables which can only take on specific values, continuous random variables have an infinite number of possible values within a given interval.
Here are some examples of continuous random variables:
1. Height: The height of an individual is a continuous random variable as it can take on any value within a specific range. For example, a person can be 5.5 feet tall, 5.6 feet tall, or any height in between.
2. Time: Time is another example of a continuous random variable. It can take on any value within a certain interval. For instance, the time it takes to complete a task can range from a few seconds to several minutes.
3. Temperature: Temperature is a continuous random variable as it can take on any value within a specific range. For example, the temperature outside can be 25 degrees Celsius, 25.5 degrees Celsius, or any temperature in between.
4. Distance: Distance is also a continuous random variable. For instance, the distance traveled by a vehicle can vary continuously, from a few meters to hundreds of kilometers.
5. Weight: Weight is a continuous random variable. It can take on any value within a specific range. For example, a person’s weight can be 150 pounds, 150.5 pounds, or any weight in between.
It is important to note that continuous random variables are characterized by probability density functions (PDFs) rather than probability mass functions (PMFs) used for discrete random variables. The probability of obtaining a specific value for a continuous random variable is essentially zero since there are an infinite number of possible values. Instead, the probability is calculated for ranges or intervals of values.
