STA 2023 Chapter Notes - Chapter 3: Sample Space, Conditional Probability, Mutual Exclusivity
Document Summary
Suppose a coin is tossed once and the up face is recorded. The result we see is called an observation, or measurement. The process of making an observation is called an experiment. ***a statistical experiment can be almost any act of observation, as long as the outcome is uncertain. An experiment is an act or process of observations that leads to a single outcome that cannot be predicted with certainty. Tossing a dice and observing the number on the up face. The six possible outcomes of this experiment are as follows: If this experiment is conducted once, you can observe one and only one of these six basic outcomes, and the outcome cannot be predicted with certainty. A sample point is the most basic outcome of an experiment: ex. There are six sample points in the sample space associated with the dice-toss experiment. The sample space of an experiment is the collection of all its sample points.
