Study Notes
Introduction to Probability
- Sample Space (S): A set containing all possible outcomes of a statistical experiment.
- Statistical Experiment: A process that generates data with outcomes subject to randomness.
- Outcome: The result of a statistical experiment.
Types of Data
- Numerical Data: Quantitative measurements or counts.
- Categorical Data: Classification based on criteria, such as defective/non-defective.
Types of Studies
- Designed Experiments: Controlled tests to observe specific outcomes.
- Observational Studies: Data collected without manipulating variables.
- Retrospective Studies: Analysis of existing historical data.
Tree Diagrams
- A method to systematically list elements of a sample space to improve clarity.
Events and Sets
- Event: A collection of sample points, representing a subset of the sample space.
- Complement of an Event (A̅, Ac, A'): The set of all elements in the sample space (S) that are not in event A.
Example: Deck of Cards
- R: The event of selecting a red card from a standard deck of 52 cards.
- R' (complement): The event of selecting a card that is not red (i.e., a black card).
Set Theory
- Universal Set (S): The entire set containing all possible elements.
- Subset (A, B): A set containing elements that are also in the universal set.
- Complements (A'): The set of elements in the universal set (S) that are not in A.
