3. Measures of Dispersion (Variability)

How "spread out" the data is.

• Qualitative (Categorical): Nominal (no order, e.g., gender) vs. Ordinal (ordered, e.g., rank).
• Quantitative (Numerical): Discrete (countable, e.g., number of cars) vs. Continuous (measurable, e.g., height).

What is Probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1 that represents the chance or probability of an event happening. Probability theory is used to model and analyze random phenomena, allowing us to make predictions and decisions under uncertainty. An Introduction to Statistics and Probability by Nurul

• Formula: $P(A_i|B) = \fracP(B\sum P(B$
