Eduqas GCSE Mathematics key terms

To divide a line segment or angle into two equal parts.

Paired values of two variables recorded for each individual or item.

The line separating the two sides of a graphical inequality. Its equation is found by replacing the inequality sign with an equals sign.

A diagram showing the minimum, lower quartile, median, upper quartile and maximum of a data set.

Simplifying a calculation or expression using operations that undo one another, or by dividing the numerator and denominator of a fraction by a common non-zero factor.

The volume a container can hold, commonly measured in millilitres or litres.

A two-dimensional grid with a horizontal $x$-axis and a vertical $y$-axis, used to locate points.

Data recorded as categories or labels, such as favourite fruit, rather than numerical measurements.

A relationship in which a change in one variable causes a change in another.

An investigation that collects information from every member of a population.

An angle at the centre of a circle, formed by two radii.

The fixed point inside a circle that is the same distance from every point on its circumference.

The fixed point from which movements to vertices are multiplied by the scale factor in an enlargement.

A straight line segment joining two points on the circumference of a circle.

The boundary of a circle; also the distance around that boundary, which is the circle's perimeter.

An endpoint separating neighbouring classes.

A range of values used to group numerical data in a frequency table.

The upper class boundary minus the lower class boundary.

A question answered by choosing from supplied response options.

The number multiplying a variable or power of a variable. In $4x^2-25x-21$, the coefficient of $x^2$ is $4$.

Lying on the same straight line.

A representation of a two-dimensional vector as $\begin{pmatrix}x\\y\end{pmatrix}$, with horizontal movement above vertical movement.

A shared denominator used to express fractions in parts of the same size before adding or subtracting them.

The constant amount added to move from one term of an arithmetic sequence to the next; it can be negative.

A whole number that divides each of two or more whole numbers exactly, without a remainder.

A number that is a multiple of each of two or more numbers.

The fixed multiplier in a geometric progression, found by dividing a term by the preceding non-zero term.

The event that $A$ does not occur, written $A'$.

Rewriting a quadratic expression in the equivalent form $a(x+p)^2+q$, containing a squared bracket and a constant.
