Dispersion : Quartile Deviation in Continuous Series
Quartile deviation is also known as the semi-interquartile range, is a measure of statistical dispersion. It indicates the spread of the middle 50% of a dataset. The quartile deviation is calculated using the first quartile (Q1) and the third quartile (Q3). The formula is: Quartile Deviation=𝑄3−𝑄1/2 Coefficient of Quartile Deviation = 𝑄3−𝑄1/𝑄3+𝑄1 Here’s a […]

Dispersion : Range
Dispersion in statistics refers to the extent to which a distribution is stretched or squeezed. Common measures of dispersion include range, variance, and standard deviation. Here’s a brief overview of the range as a measure of dispersion: Range Definition: The range is the simplest measure of dispersion. It is defined as the difference between the […]
Matrix Inverse Method
Hi Greetings of the day , Today we shall discuss the topic Inverse of a matrix in practical solutions. The inverse of a matrix is like a “reverse” for that matrix. When you multiply a matrix by its inverse, you get the identity matrix, which is like the number 1 for matrices. The identity matrix […]
Determinants (Matrix)
The determinant of a matrix is a scalar value that encapsulates several key properties of the matrix and the linear transformation it represents. It is a Scalar Quantity attached to a square matrix. Means with every square matric A there is associated a scalar quantity which is called the determinant of A . it is […]
Addition & Subtraction of Matrices
A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. The numbers in a matrix are called its elements or entries. A matrix with mmm rows and nnn columns is called an m×nm \times nm×n matrix, read as “m by n matrix”. Addition of Matrices : Matrix addition is […]
How to Solve Crammer’s Rule of Matrix
Cramer’s rule is a mathematical theorem used to solve a system of linear equations with as many equations as unknowns, provided that the system has a unique solution. It is applicable to systems of linear equations represented in matrix form. The rule is named after Gabriel Cramer, an 18th-century Swiss mathematician. Kindly check the link […]
Matrices : Meaning & Types
Matrices are a fundamental concept in mathematics, particularly in linear algebra. Here’s a detailed explanation of their meaning and types: Definition A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. The numbers in a matrix are called its elements or entries. Hence Matrix is an arrangement of rows […]
Linear Programming Method (LPP)
Linear Programming (LP) is a mathematical method used to optimize a system with linear relationships subject to certain constraints. It’s widely applied in various fields such as economics, engineering, business management, and logistics, to name a few. Here’s a basic overview of the Linear Programming method: Objective Function: This is the function you want to […]
Factor Reversibility Test : Test of Adequacy in Index Numbers
The “Factor Reversibility Test” and the “Index Number Test of Adequacy” are both methods used in econometrics and statistics to assess the validity and reliability of certain statistical models, particularly those related to index numbers and factor analysis. Factor Reversibility Test: it can be solved by practical ways . kindly Check the link In factor […]
Binomial Expansion Method of Interpolation (Two Values Missing )
The binomial method of interpolation, also known as binomial interpolation, is used to estimate missing values within a sequence of values. This method utilizes the concept of finite differences and binomial coefficients. To demonstrate the process, let’s go through the steps required to interpolate Two missing values using the binomial method. Steps for Binomial Interpolation […]
How to Find Mode in Measures of Central Tendency
MODE IN MEASURES OF CENTRAL TENDENCY In measures of central tendency, “mode” refers to the value that appears most frequently in a dataset. Unlike mean and median, which focus on the average and middle value respectively, mode highlights the most common occurrence. It’s particularly useful in categorical data or when dealing with data where certain […]
Arithmetic Mean in Measures of Central Tendency
Measures of central tendency are statistical measures that provide a single value to summarize the centre or midpoint of a dataset. The three main measures of central tendency are: Arithmetic Mean The mean is the most commonly used measure of central tendency. It is calculated by adding up all the values in a dataset and […]
Fisher’s Weighted Index Number and Other Methods to Solve Index No.
A weighted index number is a statistical measure used to track changes in a variable or a group of variables over time, taking into account their relative importance (weights). In economics and finance, weighted index numbers are often used to measure price levels, quantities, or other economic indicators. The weights usually reflect the significance or […]
INDEX NUMBER : A Brief Introduction
An index number is a statistical measure designed to show changes in a variable or a group of related variables over time. It is often used to track economic data, such as prices, quantities, or values, and can be helpful in understanding trends, inflation, cost of living, and other economic indicators.
