A datum is a single value of a single variable. See our page on Types of Data for more. Diameter is a term used in geometry to define a straight line that passes through the centre of a circle or sphere, touching the circumference or surface at both ends.
The diameter is twice the radius. Extrapolate is a term used in data analysis. It refers to the extension of a graph, curve, or range of values into a range for which no data exists, inferring the values of unknown data from trends in the known data. A factor is a number that we multiply by another number.
A factor divides into another number a whole number of times. Most numbers have an even number of factors. A square number has an odd number of factors. A prime number has two factors — itself and 1. A prime factor is a factor that is a prime number.
The mean average of a set of data is calculated by adding all numbers in the data set and then dividing by the number of values in the set.
When the data set is ordered from least to greatest, the median is the middle value. The mode is the number that occurs most times. The basic arithmetical operations are addition, subtraction, multiplication and division.
The order in which operations are carried out in a calculation is important. The perimeter of a 2-dimensional shape is the continuous line or the length of the line that defines the outline of the shape. The perimeter of a circular shape is specifically called its circumference. Our page on Perimeter explains this in more detail. Proportion is a relative of ratio. Ratios compare one part to another part, and proportions compare one part to the whole.
Proportion is related to fractions. It is an important rule that applies only to right-angled triangles. Quantitative data are numeric variables or values that can be expressed numerically, i. Qualitative data are type variables that do not have a numerical value and may be expressed descriptively, i. See our page on types of data for more. The radian is the SI unit for angular measurement. One radian is equivalent to the angle subtended at the centre of a circle by an arc equal in length to the radius.
One radian is just under The term radius is used in the context of circles and other curved shapes. It is the distance between the centre point of a circle, sphere or arc, to its outer edge, surface or circumference. In statistics, the range of a given data set is the difference between the largest and smallest values. Ratio is a mathematical term used for comparing the size of one part to another part.
End Point : The "point" at which a line or curve ends. Equilateral : A term used to describe a shape whose sides are all of equal length. Equation : A statement that shows the equality of two expressions by joining them with an equals sign. Even Number : A number that can be divided or is divisible by 2. Event : This term often refers to an outcome of probability; it may answers question about the probability of one scenario happening over another.
Evaluate : This word means "to calculate the numerical value". Exponent : The number that denotes repeated multiplication of a term, shown as a superscript above that term. The exponent of 3 4 is 4. Expressions : Symbols that represent numbers or operations between numbers.
Face : The flat surfaces on a three-dimensional object. Factor : A number that divides into another number exactly. Factoring : The process of breaking numbers down into all of their factors. Factorial Notation : Often used in combinatorics, factorial notations requires that you multiply a number by every number smaller than it. The symbol used in factorial notation is! When you see x! Factor Tree : A graphical representation showing the factors of a specific number.
Fibonacci Sequence : A sequence beginning with a 0 and 1 whereby each number is the sum of the two numbers preceding it. Figure : Two-dimensional shapes. Finite : Not infinite; has an end. Flip : A reflection or mirror image of a two-dimensional shape.
Formula : A rule that numerically describes the relationship between two or more variables. Fraction : A quantity that is not whole that contains a numerator and denominator. Frequency : The number of times an event can happen in a given period of time; often used in probability calculations. Furlong : A unit of measurement representing the side length of one square acre. Geometry : The study of lines, angles, shapes, and their properties.
Geometry studies physical shapes and the object dimensions. Graphing Calculator : A calculator with an advanced screen capable of showing and drawing graphs and other functions. Graph Theory : A branch of mathematics focused on the properties of graphs.
Greatest Common Factor : The largest number common to each set of factors that divides both numbers exactly. The greatest common factor of 10 and 20 is Hexagon : A six-sided and six-angled polygon.
Histogram : A graph that uses bars that equal ranges of values. Hyperbola : A type of conic section or symmetrical open curve. The hyperbola is the set of all points in a plane, the difference of whose distance from two fixed points in the plane is a positive constant. Hypotenuse : The longest side of a right-angled triangle, always opposite to the right angle itself.
Identity : An equation that is true for variables of any value. Integers : All whole numbers, positive or negative, including zero. Irrational : A number that cannot be represented as a decimal or fraction. A number like pi is irrational because it contains an infinite number of digits that keep repeating. Many square roots are also irrational numbers. Isosceles : A polygon with two sides of equal length. Kilometer : A unit of measure equal to meters.
Knot : A closed three-dimensional circle that is embedded and cannot be untangled. Like Fractions : Fractions with the same denominator. Line : A straight infinite path joining an infinite number of points in both directions. Line Segment : A straight path that has two endpoints, a beginning and an end. Linear Equation : An equation that contains two variables and can be plotted on a graph as a straight line. Line of Symmetry : A line that divides a figure into two equal shapes.
Logic : Sound reasoning and the formal laws of reasoning. Logarithm : The power to which a base must be raised to produce a given number.
Logarithm is the opposite of exponentiation. Mean : The mean is the same as the average. Add up a series of numbers and divide the sum by the total number of values to find the mean. Median : The median is the "middle value" in a series of numbers ordered from least to greatest. When the total number of values in a list is odd, the median is the middle entry. When the total number of values in a list is even, the median is equal to the sum of the two middle numbers divided by two.
Midpoint : A point that is exactly halfway between two locations. Mixed Numbers : Mixed numbers refer to whole numbers combined with fractions or decimals. Mode : The mode in a list of numbers are the values that occur most frequently.
Modular Arithmetic : A system of arithmetic for integers where numbers "wrap around" upon reaching a certain value of the modulus. Monomial : An algebraic expression made up of one term. Multiple : The multiple of a number is the product of that number and any other whole number. Multiplication : Multiplication is the repeated addition of the same number denoted with the symbol x. Multiplicand : A quantity multiplied by another. A product is obtained by multiplying two or more multiplicands.
Natural Numbers : Regular counting numbers. Negative Number : A number less than zero denoted with the symbol -. Nth Root : The n th root of a number is how many times a number needs to be multiplied by itself to achieve the value specified. Norm : The mean or average; an established pattern or form. Normal Distribution : Also known as Gaussian distribution, normal distribution refers to a probability distribution that is reflected across the mean or center of a bell curve. Numerator : The top number in a fraction.
The numerator is divided into equal parts by the denominator. Number Line : A line whose points correspond to numbers. Numeral : A written symbol denoting a number value.
Obtuse Triangle : A triangle with at least one obtuse angle. Octagon : A polygon with eight sides. The odds of flipping a coin and having it land on heads are one in two. Odd Number : A whole number that is not divisible by 2.
