== <span style="color: #FFFFFF;">Remembering</span> == * '''Probability Distribution''' β A mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. * '''Random Variable''' β A variable whose value is determined by the outcome of a random phenomenon. * '''Normal Distribution''' (The Bell Curve) β A symmetric distribution where most observations cluster around the central peak (Mean). * '''Poisson Distribution''' β A distribution that models the number of times an event happens in a "Fixed interval" of time (e.g., number of emails per hour). * '''Binomial Distribution''' β A distribution that models the number of "Successes" in a fixed number of "Yes/No" trials (e.g., 10 coin flips). * '''Standard Deviation (Ο)''' β A measure of the "Spread" or "Volatility" of a distribution (how far away from the center the data points are). * '''Mean (ΞΌ)''' β The "Average" or the center of the distribution. * '''Skewness''' β A measure of how "Lopsided" a distribution is (e.g., if it has a long tail to the right). * '''Kurtosis''' β A measure of how "Fat" the tails are (the likelihood of "Extreme" events). * '''Central Limit Theorem''' β The "Magic" of statistics: the idea that if you add up enough random things, they will **always** form a Normal Distribution. </div> <div style="background-color: #006400; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;">
