When three or more data elements occur together in a significant way.
The outcome factor; the variable that may change in response to manipulations of the independent variable.
double number line diagrams
A graphic diagram that shows a proportional relationship between two quantities.
Ratios that have the same value.
A part series of observations, measurements, facts, or information that is lacking data.
A variable whose variation does not depend on that of another.
A measure of center in a set of numerical data, computed by adding the values in a list and then dividing by the number of values in the list.
A measure of center in a set of numerical data. The median of a list of values is the value appearing at the center of a sorted version of the list - or the mean of the two central values if the list contains an even number of values.
A measure of central tendency that identifies the most frequently occurring score in a distribution.
Maximum value in a data set (either positive or negative).
A ratio that compares a number to 100
Distance between highest and lowest scores in a set of data.
A ratio that compares two quantities measured in different units
The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
The correspondence in size, shape, and relative position of parts on opposite sides of a median line or about central axis.
Visual models that use rectangles to represent the parts of a ratio.
The cost per unit of something.
A rate in which the second quantity in the comparison is one unit
Represents how spread out a group of data is using measures such as range, standard deviation, etc.
