Dependent Variable
The dependent variable is the result of a calculation.
The range is the distance between the smallest and largest values in a data set.
Ratio
Common Factor
A common factor of two numbers is a number that divides evenly into both numbers.
The interquartile range is one way to measure how spread out a data set is. We sometimes call this the IQR. To find the interquartile range, we subtract the first quartile from the third quartile.

Difference
Independent Variable
The independent variable is used to calculate the value of another variable.
We use the word squared to mean “to the second power.” This is because a square with side length S has an area of SxS, or S to the power of 2 .
Squared
Common Multiple
A common multiple of two numbers is a product you can get by multiplying each of the two numbers by some whole number.
a way to represent data on a number line. Data values are grouped by ranges. The height of the bar shows how many data values are in that group.

Product
Equivalent Expressions
Equivalent expressions are always equal to each other. If the expressions have variables, they are equal whenever the same value is used for the variable in each expression.
a letter that represents a number. You can choose different numbers for the value.
Variable
Frequency
The frequency of a data value is how many times it occurs in the data set.
the smallest product you can get by multiplying each of the two numbers by some whole number. Sometimes we call this the LCM.

Quotient
Long Division
Long division is a way to show the steps for dividing numbers in decimal form. It finds the quotient one digit at a time, from left to right.
represents data on a number line. The data is divided into four sections. The sides of the box represent the first and third quartiles. A line inside the box represents the median. Lines outside the box connect to the minimum and maximum values.

Coordinate Plane
The coordinate plane is a system for telling where points are.
one way to measure the center of a data set. It is the middle number when the data set is listed in order.
Median
a number that is multiplied by a variable
Coefficient
Polygon
A polygon is a closed, two-dimensional shape with straight sides that do not cross each other.
has values that are words instead of numbers.
Categorical Data
Greatest Common Factor
The greatest common factor of two numbers is the largest number that divides evenly into both numbers. Sometimes we call this the GCF.
one way to measure the center of a data set. We can think of it as a balance point.
