Ignore?
proportion
An equation that states that two ratios are equal.
independent variable
the tested varaible
dependent variable
the measure of change in the independent variable
double number line diagram
A graphic diagram that shows a proportional relationship between two quantities.
Coefficient
the decimal part
Variable
an alphabetic character representing a number, called the value, which is either arbitrary or not fully specified or unknown. It is usually a letter like x or y.
numerical expression
A mathematical phrase that has a combination of numbers and at least one operation
inequality
A mathematical sentence that shows the relationship between quantities that are not equivalent
expression
A mathematical phrase without an equal sign.
Evaluate
To find the value of a mathematical expression.
Equation
A mathematical sentence that contains an equals sign
constant
A value that does not change
algebraic expression
An expression consisting of one or more numbers and variables along with one or more arithmetic operations
y-Coordinate
The vertical measure, which is the second number in an ordered pair.
y-axis
The vertical axis on a coordinate plane.
x-Coordinate
is the first number in an ordered pair and it represents the location relative to the x-axis.
x-axis
The horizontal axis on a coordinate plane.
Four regions into which a coordinate plane is divided by the x-axis and the y-axis
plot
to place points on a graph or coordinate plane
origin
The centre point of a number line (ground floor of a hotel, freezing point on a thermometer)
ordered pair
A pair of numbers that can be used to locate a point on a coordinate plane.
coordinate system
the grid formed by the intersection of two number lines, the horizontal axis and the vertical axis
coordinate plane
A plan formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis.
coordinate pair
A pair of numbers telling where a point lies on a graph it is always (x,y)
axis
Set of boundaries on a graph. x-axis and y-axis.
upper extreme
the largest number of a set of data
tape diagram
a drawing that looks like a segment of tape, used to illustrate number relationships
table
Shows a relationship by listing the data for the two variables in pairs.
statistics
The science of collecting, organizing, analyzing, and interpreting data in order to make decisions
statistical variability
a variability or spread in a variable or a probability distribution; examples: variance, standard deviation, and interquartile range
A numerical summary of how tightly the values are clustered around the center. Measures: IQR, Standard Dev.
Range
The difference between the greatest number and the least number in a set of data.
outlier
a data value that is either much greater or much less than the median
measure of variation
A number that indicates how dispersed scores are around the mean of the distribution.
measure of center
A value at the center or middle of a data set.
Mean
the sum of all the values divided by the number of values
line plot
A diagram showing frequency of data on a number line.
lower extreme
The smallest number in a data set (box & whisker).
interquartile range
the difference between the first and third quartiles
Histogram
A bar graph depicting a frequency distribution. The height of the bars indicates the frequency of a group of scores.
distribution
The _____________________________ of a var. gives: possible values of the variance; the relative frequency of each value.
dot plot
graph with each individual entry
cluster
A number of similar things grouped together
box plot
also called a box and whisker plot
vertex
The point where two sides meet. (Shared end points of the line segments of a polygon.)
volume
measures the amount of space taken up by the object.
Scalene Triangle
A triangle with no congruent sides
Right Triangle
A triangle with one right angle.
plane
A flat surface.
perpendicular
two lines that intersect and form a right angle are
obtuse triangle
A triangle with one obtuse angle.
net
a 2-dimentional pattern that can be folded to make a 3-dimentional solid
isosceles triangle
Triangle with 2 equal sides and 2 equal angles.
intersect
to meet or cross
equilateral triangle
Triangle with a 90° angle
attribute
a quality or characteristic belonging to or associated with someone or something
acute triangle
A triangle with three acute angles.
area
the surface; Length x Width
area model
A model for multiplication problems in which the length and width of a rectangle represent the factors and the area of the rectangle represents the product.
altitude
What is the apothem called In a triangle?
Magnitude
The number of degrees a regular polygon can be rotated to map onto itself.
absolute value
The distance of a number from zero on a number line; shown by | |
Integer
The set of whole numbers and their opposites.
