Probability Guide
Probability is the mathematical model analyzing deterministic likelihoods. Values lie bounds between 0 (impossible outcome) and 1 (absolute certainty).
To trace advanced modeling, data engineers employ probability distributions:
- Gaussian Normal Distribution: Models continuous density curves around a central mean standard (μ) and variance standard deviation (σ).
- Binomial Distribution: Models the discrete count of achievements or successes across a fixed set of trials with constants.
Common FAQs
What does cumulative probability (CDF) signify?
Cumulative distribution maps the probability of an outcome being equal to or less than a specified value. For instance, obtaining three or fewer heads in coin tosses.
How is Bayes' Theorem used?
It provides a formulaic framework to update the probability of an initial hypothesis as new data, parameters, or outcomes become visible.
Why is stdDev (σ) crucial in bell curves?
Standard deviation controls the width or dispersion of the bell curve. A small standard deviation produces a tall, narrow curve, while a large standard deviation flattens and widens it.
