The continuous uniform distribution is such that the random variable X takes values between α (lower limit) and β (upper limit). We cannot have an … For instance, if a variable over a non-empty range of the real numbers is continuous, then it can take on any value in that range. What is the conflict of the story of sinigang? Continuous Variable Definition. These values may be qualitative (colour, gender, favourite singer etc) or quantitative. What is an example of continuous quantitative variable. In statistics, a variable is something that gives us data. and the second those having an infinite number of characters within a range Determined (decimal number). All Rights Reserved. Why don't libraries smell like bookstores? In the field of statistics, α and β are known as the parameters of the continuous uniform distribution. The list of fruit is nominal.

All Rights Reserved. The data collected for a numeric variable are quantitative data. A variable is something that can take different values. An ordinal variable can also be used as a quantitative variable if the scale is numeric and doesn’t need to be kept as discrete integers. How long will the footprints on the moon last?
