A
Any collection of members in a population.
What is a sample?
The result of a single trial of a chance experiment.
What is outcome?
The variation in the values of a statistic among samples of the same size from the same population.
What is sampling variability?
A number that summarizes data collected from the entire population.
What is a population characteristic?
Parts per 100.
What is a percent?
A procedure in which we conduct a chance experiment that closely resembles a real situation of interest.
What is a simulation?
A sample in which every member of the population has an equally likely chance of being chosen.
What is a random sample?
A mathematical representation of a chance experiment that accounts for all outcomes within the sample space and assigns a probability to each outcome.
What is a probability model?
A measure of how likely it is that an event will happen. We describe it by using a number between 0 and 1.
What is probability?
A number, or the result of a calculation.
What is value?
Any entire collection of people, animals, or objects that someone is interested in learning about. Each person, animal, or object in the population is called a member.
What is a population?
The value of the ratio of the number of members of a population that have a specified characteristic to the total number of members in the population.
What is a population proportion?
A set of one or more possible outcomes. A simple event is an event with only one outcome. A compound event is an event with multiple outcomes.
What is an event?
Exactly the same amount or value.
What is equal?
Shows the relative sizes of two or more values.
What is a ratio?
The probability of an event that is calculated after observing the outcomes from multiple trials of the chance experiment. It is the value of the ratio to the number of observations of the event to the number of trials conducted.
An experiment where you repeatedly conduct a trial or a process that can have two or more results due to uncertainty and then observe the results.
What is a chance experiment?
The distribution of the values of a statistic calculated for repeated samples of the same size from the same population.
What is sampling distribution?
A collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.
What is data?
How many parts of a whole; the numerator says how many parts and the denominator says how many equal parts the whole is divided into.
What is a fraction?
A geographical representation that displays all possible sequences of outcomes in a multistage experiment. The tree starts by displaying 2 or more branches that represent the possible outcomes in the first stage of the experiment. Each of those branches then splits off into the possible outcomes for the second stage. If there are more stages, this process continues until all possible sequences of outcomes are displayed. The total number of branches at the end of the tree is the number of possible outcomes in the sample space of the multistage experiment. Each individual path of branches, from beginning to end, is a unique sequence of single-stage results that forms an outcome of the multistage experiment.
What is a tree diagram?
The expected relative frequency of an event when conducting many trials of the chance experiment. When all outcomes in the sample space are equally likely, it is the number of outcomes that give that event divided by the number of possible outcomes.
What is theoretical probability?
A number that summarizes data collected from a sample.
What is a sample statistic?
How far, on average, all values are from the middle.
What is mean absolute deviation?
The result of adding.
What is the total?
