Median formula

Definition of Median formula:
Median (a): constituting the middle value of an ordered set of values is called median.
The set of values arranged in Lower value to higher value (increasing order).If the set of data has an odd number of entries, the median is the middle value of the set after sorting the list into increasing order.
Need help with limit calculator
If the set of data has an even number of means , the median is equal to the sum of the two middle value (after sorting) numbers and divided by two.
In probability theory, a median is described as the number of separating the higher half of set of values, a population, or a probability.

The general formula for the median is as follows,

M=(n+1)/2

here,

M - median,

n - total number of values present in the set.

Linear Regression

Linear Regression Formula

Linear regression analyzes the relationship between two variables, X and Y. For each subject (or experimental unit), you know both X and Y and you want to find the best straight line through the data. In some situations, the slope and/or intercept have a scientific meaning. In other cases, you use the linear regression line as a standard curve to find new values of X from Y, or Y from X. A regression is a statistical analysis assessing the association between two variables. It is used to find the relationship between two variables.

Linear Regression Formula:

Regression Equation(y) = a + bx

Slope(b) = (NΣXY - (ΣX)(ΣY)) / (NΣX2 - (ΣX)2)
Intercept(a) = (ΣY - b(ΣX)) / N


A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable.

Will soon be back with Linear functions and Inequalities.

Arithmetic Progression

Geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed non-zero number called the common ratio. A sequence, such as the numbers 1, 3, 9, 27, 81, in which each term is multiplied by the same factor in order to obtain the following term. Also called geometric sequence. It is a Sequence of numbers where the ratio between any two adjacent numbers is constant.

For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2.

Progressions and types are different one among them is Arithmetic Progression.

Arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant.

A finite portion of an arithmetic progression is called a finite arithmetic progression and sometimes just called an arithmetic progression.

What is Trigonometry?

Trigonometry is the branch of mathematics that deals with triangles, circles, oscillations and waves. The study of angles and of the angular relationships of planar and three-dimensional figures is known as trigonometry. The trigonometric functions of angles are the ratio of the various sides of a triangle.

Trigonometry is the science of angular magnitudes and the art of applying the principles of this science to the solution of trigonometry problems. Trigonometry considers the properties of angles and certain ratios associated with angles, and applies the knowledge of these properties to the solution of triangles and various other algebraic and geometric problems. Incidentally trigonometry considers also certain time-saving aids in computation such as logarithms, which are generally employed in the solution of triangles.
