Joint Probability Distributions help analyze the relationship between multiple random variables.
Marginal distributions provide distributions of individual variables independent of others.
Independence of random variables signifies that their joint distribution equals the product of their marginals.
Functions that assign real numbers to outcomes in a sample space, categorized into discrete and continuous.
A function that describes the probability behavior of two or more random variables simultaneously.
The probability distribution of a single variable obtained by summing or integrating over the other variables.
Describes the distribution of one variable given the value of another variable.
Two random variables are independent if the joint probability equals the product of their individual probabilities.
The mean of a random variable, calculated as the weighted average of all possible values.
A measure of the joint variability of two random variables, indicating the direction of their linear relationship.
A normalized measure of the strength and direction of the linear relationship between two variables.
