A univariate probability distribution is a statistical function that describes the likelihood of a single random variable taking on various values. This distribution is fundamental in the fields of statistics, data analysis, and data science, as it provides insights into the behavior and characteristics of data points within a dataset.

- What is: Univariate Distribution
Univariate distribution. In statistics, a univariate distribution is a probability distribution of only one random variable. This is in contrast to a multivariate distribution, the probability distribution of a random vector (consisting of multiple random variables).
A univariate distribution is the probability distribution of a single random variable. For example, the energy formula (x – 10) 2 /2 is a univariate distribution because only one variable (x) is given in the formula. In contrast, bivariate distributions have two variables and multivariate distributions have two or more.
Univariate distribution refers to the probability distribution of a single random variable. It provides a comprehensive framework for understanding how values of that variable are spread over a range of possible outcomes. In statistics, univariate distributions are essential for analyzing data that involves only one variable, allowing ...

A probability distribution is an idealized frequency distribution. A frequency distribution describes a specific sampleor dataset. It’s the number of times each possible value of a variable occurs in the dataset. The number of times a value occurs in a sample is determined by its probability of occurrence. Probability is a number between 0 and 1 th...
A discrete probability distribution is a probability distribution of a categorical or discrete variable. Discrete probability distributions only include the probabilities of values that are possible. In other words, a discrete probability distribution doesn’t include any values with a probability of zero. For example, a probability distribution of ...
A continuous probability distribution is the probability distribution of a continuous variable. A continuous variable can have any value between its lowest and highest values. Therefore, continuous probability distributions include every number in the variable’s range. The probability that a continuous variable will have any specific value is so in...
You can find the expected value and standard deviation of a probability distribution if you have a formula, sample, or probability table of the distribution. The expected value is another name for the mean of a distribution. It’s often written as E(x) or µ. If you take a random sample of the distribution, you should expect the mean of the sample to...
Null distributions are an important tool in hypothesis testing. A null distribution is the probability distribution of a test statistic when the null hypothesis of the test is true. All hypothesis tests involve a test statistic. Some common examples are z, t, F, and chi-square. A test statistic summarizes the sample in a single number, which you th...

What is Univariate Analysis? Univariate analysis is the simplest form of analyzing data. “Uni” means “one”, so in other words your data has only one variable. It doesn’t deal with causes or relationships (unlike regression ) and it’s major purpose is to describe; It takes data, summarizes that data and finds patterns in the data.
