Probability of Independent Events. "Probability" (or "Chance") is how likely something is to happen. So how do we calculate probability? Probability of an event happening = Number of ways it can happen Total number of outcomes. Example: what is the probability of getting a "Head" when tossing a coin? Number of ways it can happen: 1 (Head)
Rolling an "even number" (2, 4 or 6) is an event. Events can be: Independent (each event is not affected by other events), Dependent (also called "Conditional", where an event is affected by other events) Mutually Exclusive (events can't happen at the same time) Let's look at each of those types.

Independent events in statistics are those in which one event does not affect the next event. More specifically, the occurrence of one event does not affect the probability of the following event happening. Here are three quick examples of independent events: Flipping a coin.
Independence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes. Two events are independent, statistically independent, or stochastically independent [1] if, informally speaking, the occurrence of one does not affect the probability of occurrence of the other or, equivalently, does not affect ...
Having independent and identically distributed (IID) data is a common assumption for statistical procedures and hypothesis tests. But what does that mouthful of words actually mean? That’s the topic of this post! And, I’ll provide helpful tips for determining whether your data are IID.
16 sie 2024 · An independent variable is defined as a variable that is changed or controlled in a scientific experiment. The independent variable represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test his or her dependent variable.
