Algebraic expression (conceptual modeling)

an algebraic expression in variables is an expression constructed with the variables and algebraic numbers using addition, multiplication, and rational powers.
Conceptual modeling  An abstract model (or conceptual model) is a theoretical construct that represents something, with a set of variables and a set of logical and quantitative relationships between them 

Bias

The other source of deviation is known as the bias, or systematic error, which has to do with how the observations are made, how the instruments are set up to make the measurements, and most of all, how these observations or measurements are tallied and summarized to come up with an estimate of the true parameter


Composite

A composite number is a positive integer which is not prime and not equal to 1. That is, is composite if , with and natural numbers both not equal to 1.


Conjecture (with data)

a statement which the speaker has reason to believe is correct even though the speaker cannot prove the statement


Coordinate plane (ordered pairs)

It is formed by a horizontal number line, called the xaxis, and a vertical number line, called the yaxis. The two axes intersect at a point called the origin.


Degrees (angle)

Degree – the unit of measure used to state the size of an angle


Equation (solving)

A mathematical sentence where the left size of the equals sign has the same value as the right side.


Evaluate

A term used in algebra
To evaluate an expression means to find a numerical value for it, to “work it out” 

Formula

A mathematical rule written using symbols, usually as an equation describing a certain relationship between quantities


Function

Like an input/output machine; it repeats a rule to determine how each input will be changed to produce each output


Inverse

Opposite, reverse operations


Measures of central tendency

Mean, median, and mode, In mathematics, an average or central tendency of a set (list) of data refers to a measure of the "middle" of the data set.


Odds (probability)

the probability that one thing is so or will happen instead of another <the odds are good it will rain today> b : the ratio of the probability of one event to that of an event that can happen instead <the odds of success to failure in throwing a six with two dice are 1 to 5>


Order of operations

The order in which operations should be done


Percent

Number out of 100


Prime

Number that has exactly two factors
Number that can only be divided evenly by itself and one 

Probability

The chance that a particular outcome will occur, measured as a ratio of the total of possible outcomes


Properties of shapes and figures

Geometry is the study of the properties of shapes and figures


Proportion

the size, number, or amount of one thing or group as compared to the size, number, or amount of another <the proportion of boys to girls in our class is three to one> : a statement of the equality of two ratios (as 4/2 = 10/5)  compare


Random

Chance pick from a number of items, like drawing a number out of a hat


Rate of change

A change in one quantity with respect to another quantity is called a rate of change.


Ratio

Comparative value of two or more amounts compared to their total


Reciprocal

One of two numbers whose product is 1; multiplicative inverse of a number (except zero)


Sample

Section of a whole group; to get data from part of a group and use it to give information about the whole group


Scale drawing

A scale drawing is a drawing that represents a real object.
The scale of the drawing is the ratio of the size of the drawing to the actual size of the object. 

Simplify

To reduce the numerator and denominator in a fraction to the smallest numbers possible


Simulation

A simulation is an imitation of some real thing, state of affairs, or process. The act of simulating something generally entails representing certain key characteristics or behaviors of a selected physical or abstract system.


Statistics

The collection, organization, presentation, interpretation, and analysis of data; generic word for any kind of measurement or count; a statistic is a single number, computed from a sample, that summaries some characteristic of a population


Stemandleaf plot

A data display that shows groups of data arranged by place value


Tessellation

Patterns of shapes that fit together without any gaps


Transformation

A change in position or size, including reflection (a flip), translation (a slide), rotation (a turn), and enlargement (a zoom)


Tree diagram

In statistical methods, a tree diagram is a schematic diagram which shows all possible outcomes of an event and the probabilities of each


Volume

Amount of space occupied by an object
