Continuous Variables vs. Discrete Variables: A variable holding any value between its maximum value and its minimum value is what we call a continuous variable; otherwise, it is called a discrete variable. So, how the data are first encoded rarely inhibits their use in other ways and transformation to other forms. Why is continuous data important to understand? Our career-change programs are designed to take you from beginner to pro in your tech careerwith personalized support every step of the way. and to figure out which mathematical functions you might want to use for advanced analysis (such as, do you need differential or integral calculus?). To see this, we use that the CDF $F$ is already (by definition) continuous on the right, so that $F$ is continuous if and only if is continuous on the left. If this distribution function is continuous (as a function in ordinary calculus) then we say that $X$ is a continuous random variable.

For instance, weight can be rounded to the nearest tenth, or hundredth, down to the actual sensitivity of the instrument used to measure weight; it remains discrete in the sense that you can enumerate the possible values starting with 0.0, 0.1, 0.2, , but it's also continuous in the sense that theoretically it makes sense to consider weight as real valued. However, the count of 9.5 people standing in a queue doesnt make sense (half a person?). If, voter-names are known, and, it holds voter-names, then variable is nominal. For more introductory posts, you should also check out the following: Standard deviation vs standard error: Whats the difference? $$ You can calculate the average (center) and the standard deviation (spread). Cross Validated is a question and answer site for people interested in statistics, machine learning, data analysis, data mining, and data visualization. Is money discrete or continuous? We could categorize variables according to the levels of measurement, then we could have 4 scales (groups) with the following rules: nominal: attributes of a variable are differentiated only by name (category) and there is no order (rank, position). These cookies ensure basic functionalities and security features of the website, anonymously. But if a continuous model such as $\mathsf{Norm}(\mu = 10000, \sigma=2000)$ is approximately correct for a particular group of cardholders, that is easer to deal with than a discrete random variable with something like $1\,200\,000$ discrete values spaced 1-cent apart.
