When working with various forms of data, it is essential to know them. Data can be numerical or descriptive, and both forms can be discrete or continuous. You can evaluate and interpret your data more effectively if you understand the differences between discrete and continuous data. Both types...
A probability distribution is a formula or a table used to assign probabilities to each possible value of a random variable X. A probability distribution may be either discrete or continuous. A discrete distribution means that X can assume one of a countable (usually finite) numb...

Cat has a master's degree in education and is currently working on her Ph.D.Cite this lesson Data refers to statistics and other types of information collected for research and analysis. Data comes in various types, including discrete and continuous. Explore the definition and examples of data...
Values of x that are used in a function and domain, or all x values, can be used as either discrete or continuous domains. Explore how x values stand alone and do not have intervals between them in discrete domains, while x values in continuous domains do have an interval. Discrete &...
As mentioned in earlier chapters, the probability distributions can be classified into discrete and continuous distributions, based on the nature of the random variable of interest. First we will discuss discrete distributions and some continuous distributions derived from discrete distributions. 展开 ...

In addition, you can calculate the probability that an individual has a height that is lower than 180cm. Therefore, you can use the inferred probabilities to calculate a value for a range, say between 179.9cm and 180.1cm. Observing the continuous distribution, it is clear that the mean is ...
A discrete probability distribution counts occurrences that have countable or finite outcomes. Discrete distributions contrast with continuous distributions, where outcomes can fall anywhere on a continuum. Common examples of discrete distribution include the binomial, Poisson, and Bernoulli distributions. ...
