A one-to-one relation in math means that for every value in the range, there's at most one value that maps to it. If you think of relations as people sitting on a bus, this means that no one is sharing a seat. More often, mathematicians talk about one-to-one functions (formally called injections) - these are just one-to-one relations that happen to be functions :-). If we write the function as y=f(x), the condition for it being one-to-one is that if f(a)=f(b), then a=b. When looking at the graph of a relation, we can determine if it's one-to-one by the horizontal line test: if any horizontal line drawn on the graph intersects the relation at most once, it is one-to-one. On the other hand, if a horizontal line intersects the relation twice, the relation is not one-to-one. For example, y=x^2 is not a one-to-one relation: (-1)^2 and 1^2 both get mapped to 1. We can see this in the graph of y=x^2 because a horizontal line above the x-axis will intersect the graph twice. y=x^3, on the other hand, is a one-to-one relation. Because the cube of a negative number stays negative, no two numbers get sent to the same number by cubing them.

In mathematics, if the data in a set shows no relation, then that set shows no trend.
what I would like to know is the importance of statistics in mathematics in relation to aspects like the mode,median & the mean and how one can explain this in a 2000 word essay
There is no direct relationship. Trigonometry can be used in criminology as can many branches of mathematics and of science.
Algebra is a branch of mathematics concerning the study of structures, relation and quantity. Together with geometry, analysis, combinatorics and number theory, Algebra is one of the main branches of mathematics.

A transgression in mathematics mean that there is a relation between elements of the n-th in a cluster of the fibre, and the n+1th cluster of the base of a fibre space.
The shape of a rose flower is known as a logarithmic spiral, which is a type of spiral that grows by equal factors in every direction. This spiral can be described mathematically using the equation r = a * e^(b*theta), where r is the distance from the center of the spiral, theta is the angle of rotation, and a and b are constants. The petals of a rose flower grow in this pattern to optimize exposure to sunlight and facilitate pollination.

Statistic use mathematics to show relation of sets of datas.
In business mathematics are applied in various instances. To start, Accounting, which provides basic needs of profit, payroll, and logistics. Secondly, engineering and statistics. They aid in providing company with a dissected approach to information.
A relation is a mapping from elements of one set, called the domain, to elements of another set, called the range. The function of the three terms: relation, domain and range, is to define the parameters of a mapping which may or may not be a function.
I do love a spot of maths. It is rather enlightening. Maths is used in EVERYTHING. AND DON'T YOU FORGET IT. it is the most amazing thing ever. Even though i am mega-cool, man.
