Erwartung

"Erwartung" is a German term that translates to "expectation" or "expected value" in English, often used in probability and statistics. It describes the average outcome you would anticipate if an experiment or process were repeated many times. For example, if you roll a fair six-sided die, the Erwartung of the result is 3.5, meaning over many rolls, the average value tends toward 3.5. It helps in understanding the central tendency of random variables, providing a single summary figure that captures the overall expected outcome based on their probabilities.
