Regular
Pyramid
Slant Height
The sum of all the areas of a
solids lateral faces
The sum of all the areas of a solid’s
sides.
A pyramid whose base is a regular
polygon. The lateral faces of a
regular pyramid are congruent
isosceles triangles, which
intersect at the pyramid’s vertex.
The altitude or height of each
lateral face of a pyramid.
Similar Solids
Solids that have the same shape
and their corresponding linear
measures are proportional.
Outcome
Any of the possible results of an
action
Event
One outcome or collection of
outcomes
Sample Space
An organized list of outcomes. Used
to determine the total number of
possible outcomes for an event.
Tree Diagram
A specific type of an organized list
Fundamental
Counting
Principle
Random
Composite
Experiment
Uses multiplication of the number of
ways each event in an experiment
can occur to find the number of
possible outcomes in a sample
space.
Outcomes occur at random if each
outcome is equally likely to occur.
An event that consists of two or
more simple events.
Independent
Events
Dependent
Events
Two or more events in
which the outcome of the
event does not affect the
outcome of the other
event(s)
Two or more events in which
the outcome of one event does
affect the outcome of the other
event or events
Experimental
Probability
An estimated probability based on
the relative frequency of positive
outcomes occurring during an
experiment
Theoretical
Probability
Probability based on known
characteristics or facts.
Simulation
An experiment that is designed to
act out a given situation
Sample
A randomly-selected group chosen
for the purpose of collecting data
Population

Sample
Simple
Random
Sample
Stratified
Random
Sample
The entire group of items or
individuals from which the
samples under consideration
are taken
A sample that is selected so that it
is representative of the entire
populations
Each item or person in the
population is as likely to be chosen
as any other.
The population is divided into
similar, non-overlapping groups. A
simple random sample is then
selected from each group.
Systematic
Random Sample
The items or people are selected
according to a specific time or
interval
Biased
Sample
One or more parts of the population
are favored over the others
Convenience
Sample
A sample that includes
members of a population that
are easily accessed.
Voluntary
Response
Sample
A voluntary response sample
involves only those who want to
participate in the sample.
Histogram
A type of bar graph used to display
numerical data that have been
organized into equal intervals.
Circle Graph
A graph used to compare parts of a
data set to the whole set of the
data. The entire circle represents
the whole set, so the percents in a
circle graph add up to 100.
Measure of
Central
Tendency
Measure of
Variation
Numbers that describe the center of
the set of data. The most common
measures are:
Mode: number occurring most often
Mean: sum of all the data divided by the
number of items in the set
Range: difference between the greatest
number and the least number in the set
Median: middle number of an ordered set
Used to describe the distribution or
spread of the data set.
