Descriptive Analytics: Module V – Probability Distributions and Data Modeling

Most business decisions involve uncertainty. Customer demand can change, delivery times can vary, equipment can fail, and actual sales may differ from forecasts. Probability provides a structured way to represent and analyze this uncertainty.

In this module, you will examine how probability concepts and probability distributions can be used to describe uncertain events and model possible business outcomes. You will explore relative frequency, basic probability concepts, random variables, and probability distributions, while learning how historical data can help estimate the likelihood of future outcomes.

Probability models do not eliminate uncertainty. Instead, they help analysts quantify uncertainty, evaluate possible outcomes, and make better-informed decisions when results cannot be known with certainty.

Excel will be used to organize data, calculate probabilities, and explore probability distributions in practical business situations.
