Let's say 5,000 kilograms. so basically discrete random variables are integer and continuous random variable can take non-integer values? Continuous variables, unlike discrete ones, can potentially be measured with an ever-increasing degree of precision. of the possible masses. Specifically, you learned that there are two main types of variables you will encounter in statistics: qualitative and quantitative variables. This is a matching worksheet. Multi means many. This is simple to remember thanks to words like multiple or multitude, all of which mean many. Studying two or more variables and the relationships between them. Discrete mathematics is the study of mathematical structures that can be considered "discrete" (in a way analogous to discrete variables, having a bijection with the set of natural numbers) rather than "continuous" (analogously to continuous functions).Objects studied in discrete mathematics include integers, graphs, and statements in logic. values are countable. There are three quartiles denoted by Q 1, Q 2 and Q 3 divides the frequency distribution in to four equal parts.
