But keep up the good work! Everyone makes mistakes and only from them we learn and better ourselves! D There seem to be enough problems in understanding statistical methods as it is. ANd since there seem to be many misunderstandings with the mathematical theory behind it I think the time and sweat to learn it is better spend elsewhere. PPS: I really don't get why the IQR is tought in the 6th grade since even bachelor-graduates don't use it that much in most cases. But it doesn't mean you should repeat it. PS: I know you are not the only ones that are making this mistake. So please please plaese make a new video in which you at least aknowledge that there are different definitions of the IQR and in your case even the Quantiles(Or here Quartiles which are the 0.25-, 0.50- and 0.75-Quantiles particularly) Now I know that the IQR is defined differently from field to field, but as far as I know the quantile function x_p is defined the same for all fields of science or at least in statistical mathematics, so how come you are using it so inconsistently?Īnd as far as I experienced it 'my' method and the method in the video will get the same results more often than not but here it's inconsistent.Īlso just as a sidenote: The algorithm at gets another IQR of 7 for that data set. With that I would get a IQR=Q_3 - Q_1= 12-6=6 I learned that a p-quantile for any number 0 whats a range in math

There are 5 commonly used ways to represent a relation. How is a Relationship in Math Represented? The graph of this relation will be a parabola. y = x 2 is an example of a relation equation. When a relation is expressed in the form of an equation it is known as a relation equation.

There are four other types of relations based on mapping. There are nine different types of relations in math. What are the Different Types of Relations in Math? Suppose there are two sets X = is a relation but not a function as 1 is mapped twice (to both 2 and 3). In other words, a relation says that every input will produce one or more outputs. Then the cartesian product of X and Y, represented as X × Y, is given by the collection of all possible ordered pairs (x, y). Let x ∈ X (x is an element of set X) and y ∈ Y. Suppose there are two sets given by X and Y. Relations in maths is a subset of the cartesian product of two sets. It can also be said that a function is a subset of a relation. Furthermore, special types of relations that can be used to establish a correspondence between two quantities are known as functions. They help to map the elements of one set (known as the domain) to elements of another set (called the range) such that the resulting ordered pairs are of the form (input, output). Relations in math are used to describe a connection between the elements of two sets.
