Chapters 5 Stats

The measure of the likelihood of a random phenomenon or chance behavior occurring.

• Statistic

• Probability

• Outcome

• Experiment

A random result of a short-term experiment.

• Outcome

• Statistic

• Event

• Sample Space

A process with uncertain results which can be repeated.

• Event

• Experiment

• Outcome

• Sample Space

As the number of trials of a probability experiment increases, the proportion at which a certain outcome is observed gets closer to the probability of the outcome.

• The Law of Large Numbers

• Empirical Probability

• Classical Probability

• Subjective Probability

The collection of all possible outcomes of a probability experiment; denotes as "S".

• Outcomes

• Sample Space

• Tree Diagram

• Probability Model

Any collection of an outcome; can be a single outcome (simple: denotes as lower-case letters) or multiple outcomes (denoted as upper-case letters).

• Event(s)

• Probability

• Statistic(s)

• Sample Space

The total number of outcomes (number of outcomes in a sample space).

• Events

• Sample Space

• Experiment Result

• n

• True

• False

The sum of the probabilities of all the outcomes must equal 1. Every probability model MUST obey this rule.

• True

• False

It gives all the possible outcomes of a probability experiment and the probability of each outcome.
