But thanks for the answer, even if I don't understand the concept at least I know what it means. The information on that Wiki really cleared it up for me. Add a comment. Winter BBot BBot 6 6 silver badges 18 18 bronze badges. In the expression 6 x , 6 is the coefficient and x is the variable. The circumference is the length of the distance around the edge of a circle. It is a type of perimeter that is unique to circular shapes.

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.

I'm showing my age. I have seen variants of these used by people who predate widespread knowledge of computer programming. It would be interesting to know the earliest uses of a special symbol for this and what symbols were chosen. Nine times out of ten it is the left, but the flexibility is nice. There might have been an e in there, but not legible. Show 15 more comments.
