words that start with
C,E,R
C,E,R
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 (Lesson 2)
Chance experiment
Any collection of members of a population (Lesson
sample
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. (Lesson 4)
theoretical probability
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. (Lesson 11)
population
the value of a range of values.
Median
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 of the number of observations of the event to the number of trials
conducted. (Lesson 2)
Empirical probability
A number that summarizes data collected from a sample (Lesson 11)
sample statistic
A graphical representation that displays all possible sequences of outcomes in a multistage experiment. The
tree starts by displaying two or more branches that represent the possible outcomes in the first stage of the
experiment. Each of those branches then splits off to the possible outcomes in 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. (Lesson 5)
tree diagram
A number that summarizes data collected from the entire population (Lesson 11)
population characteristic
a numerical quantity that is not a whole number
fraction
the statistical data comprising categorical variables of data that are converted into categories
categorical data
The distribution of the values of a statistic calculated for repeated samples of the same size from the same
population (Lesson 14)
sampling distribution
numerator
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 (Lesson 16)
population proportion
The result of a single trial of a chance experiment (Lesson 2)
outcome
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 more than one outcome. (Lesson 2)
event
sampling variability
The variation in the values of a statistic among samples of the same size from the same population (Lesson 14)
sampling variability
the data that is in the form of numbers, and not in any language or descriptive form.
Numerical data
A measure of how likely it is thet an event will happen, We describe probability by using a number between O
and 1, (Lesson 1)
probability
the regard that something is held to deserve; the importance, worth, or usefulness of something.
value
A sample in which every member Of the population has an equally likely chance Of being chosen (Lesson 12)
random sample
A procedure in which we conduct a chance experiment that closely resembles a real situation of interest
(Lesson 9)
simulation
a whole or complete amount,
Total
A mathematical representation of a chance experiment that accounts for all outcomes within the sample
space and assigns a probability to each outcome (Lesson 4)
probability model
the action or process of observing something or someone carefully or in order to gain information.
