A numerical method is the same as an algorithm, the steps required to solve a numerical problem. Algorithms became very important as computers were increasingly used to solve problems. It was no longer necessary to solve complex mathematical problems with a single closed form equation. See link on algorithm. According to Wikipedia: Numerical analysis is the study of algorithms for the problems of continuous mathematics (as distinguished from discrete mathematics). See link on numerical analysis. An expanded definition offered by K.E. Atkinson is: Numerical analysis is the area of mathematics and computer science that creates, analyzes, and implements algorithms for solving numerically the problems of continuous mathematics. Such problems originate generally from real-world applications of algebra, geometry and calculus, and they involve variables which vary continuously; these problems occur throughout the natural sciences,Social Sciences, engineering, medicine, and business. Numerical analysis courses typically are offered as part of Industrial engineering (Operations research), applied mathematics, computer science. Simulation, operations research and computer science are very interrelated

What are the differences between semi-quantitative and quantitative methods of data analysis?
Semi-quantitative methods involve assigning categories or rankings to data, while quantitative methods involve measuring and analyzing numerical data. Semi-quantitative methods provide a general sense of trends, while quantitative methods offer precise numerical values for analysis.

Definition of numerical analysis?
Numerical Analysis - an area of mathematics that uses various numerical methods to find numerical approximations to mathematical problems, while also analysing those methods to see if there is any way to reduce the numerical error involved in using them, thus resulting in more reliable numerical methods that give more accurate approximations than previously.

What is the difference between numerical analysis and numerical methods?
Short answer; there isn't any.Long/picky answer; numerical methods tend to look at, surprisingly, numerical methods on solving certain problems such as finding answers to equations (finding fixed points), calculating errors and really just doing calculations using these methods.Numerical analysis on the other hand, does all of this but also looks deeper into why error occurs from these methods and looks into ways of adjusting these methods or developing better ones that reduce the errors given so as to obtain much more accurate approximations to the solution you are trying to find for a given problem.

What are the differences between Euler and Runge-Kutta methods in numerical analysis and which method is more accurate for solving differential equations?
The main difference between Euler and Runge-Kutta methods in numerical analysis is the way they approximate the solution of differential equations. Euler method is a simple and straightforward approach that uses a first-order approximation, while Runge-Kutta method is more complex and uses higher-order approximations to improve accuracy. In general, Runge-Kutta method is more accurate than Euler method for solving differential equations, especially for complex or stiff systems.

What is the difference between numerical methods and analytical methods?
In analytical analysis we should use related formulas to obtain the analysis results. However many systems possess complex functionality that it is hard to track the system behavior by formulas. in such cases, we should simulate the system and analyze it in some well defined situation to estimate its behavior.
