Vocab for math

Slide 1

• Chance Experiment
• Consists of observing a single outcome of a chance process

Slide 2

• Chance Process
• Any process that is repeatable and results in 1 of 2 or more well-defined outcomes each time it is repeated

Slide 3

• Event
• A subset of outcomes of the sample space

Slide 4

• Frequency of an event
• The number of trials for which the event occurred in performing a fixed number of trials of a chance process

Slide 5

• Long Run relative frequency
• The number that the relative frequencies get closer and closer to as more and more trials are performed

Slide 6

• Population
• Any entire collection of people, animals, plants, or things that someone is interested in learning about

Slide 7

• Probability
• The number between 0-1 that measures the chance that an event will occur

Slide 8

• Probability model
• A mathematical representation of a chance process

Slide 9

• Probability simulation
• The use of a random number generator to generate outcomes that are consistent within a given probability model

Slide 10

• Random sample
• A sample that is selected by a process that ensures that every member of the population has the same chance of being included in the sample

Slide 11

• Relative frequency of an event
• The value given by the frequency of the event divided by the total number of trials

Slide 12

• sample
• Any subset of a population

Slide 13

• Sample space
• The set of all possible outcomes from a sample

Slide 14

• Sample statistic
• The mean (average) that is calculated from a sample

Slide 15

• Statistical inference
• The process of drawing conclusions about population parameters using simple statistics

Slide 16

• Uniform Probability Model
• A model that assigns the same probability for all simple events of a sample space
