2.1Variables and Data Variable:某物或某人的某一特征和其他个体不同。 quantitative variables:定量变量either discrete(可以被数)or continuous.(A continuous variable is a variable whose possible values form some interval of Numbers)Ty
In an introductory stats class, one of the first things you’ll learn is the difference between discrete vs continuous variables.Discrete variablesare countable, distinct values such as number of letters in a word or number of traffic accidents in a day. On the other hand,continuous ...
These observables do not have eigenvalues, but a continuous spectrum; hence, the term "continuous﹙ariable systems" has been coined to describe the situation. A class of non〨aussian states plays a central role in quantum optical systems. Gaussian states play a central role in continuous﹙aria...
4. Discrete vs continuous data: Examples Now we have a rough idea of the key differences between discrete vs continuous variables, let’s look at some solid examples of the two. Examples of discrete variables Shoe size Numbers of siblings Cars in a parking lot Days in the month with a tem...
There are times when continuous variables can be treated as discrete variables. Think about it—is age discrete or continuous? Given that you know the time of birth, you can accurately measure someone's age right down to the second. Age is a continuous variable in this case. However, we ...

Learn the true differences and similarities between discrete and continuous data. See examples and discover how to measure and utilize this data to gain profitable insights.
Continuous random variables must satisfy the following: Probabilities for all ranges of X are greater than or equal to zero: P(a ≤ X ≤ b) ≥ 0. The total area under the curve equals one: P(-∞ ≤ X ≤ + ∞) = 1. The likelihood of X falling within a particular range of values...
And unlike discrete data, continuous data requires measurements and is not simply counted. If your captured data has these characteristics, you're evaluating continuous data. Variables change with time Variables have different values at any given interval Variables are random and may or may not be ...
