Standard Deviation vs Mean In descriptive and inferential statistics, several indices are used to describe a data set corresponding to its central tendency, dispersion and skewness. In statistical inference, these are commonly known as estimators since they estimate the population parameter values. Central tendency refers to and locates the center of the distribution of values. […]
Difference Between Phase Velocity and Group Velocity
Phase Velocity vs Group Velocity Phase velocity and group velocity are two very important concepts in physics. They play a vital role in fields such as wave mechanics, optics, quantum mechanics and even sound engineering. It is vital to have a solid understanding in both phase velocity and group velocity in order to excel in […]
Difference Between Linear Equation and Nonlinear Equation
Linear Equation vs Nonlinear Equation In mathematics, algebraic equations are equations, which are formed using polynomials. When explicitly written the equations will be of the form P(x) = 0, where x is a vector of n unknown variables and P is a polynomial. For example, P(x,y) = 4×5 + xy3 + y + 10 = […]
Difference Between Unleaded and Super Unleaded
The key difference between unleaded and super unleaded petrol is that Unleaded petrol has minimum RON 91 whereas super unleaded petrol has minimum RON 97-98. The term RON stands for Research Octane Number. It is a measure of the effect of fuel on an engine. We can measure it by running the fuel in a […]
Difference Between Unleaded and Premium Unleaded
Unleaded vs Premium Unleaded Petrol is a volatile liquid form of hydrocarbon fuel. It is isolated by fractional distillation of petroleum and is used as a fuel in the internal combustion engines. Additional compounds have mixed with petrol in order to enhance its usage in engines. Hydrocarbons like isooctane or benzene and toluene are added […]
Difference Between Food Additives and Preservatives
Food Additives vs Preservatives | Food Preservative vs Food Additive Among the ample amounts of problems occurring in the food industry, food deterioration and quality defects play vital roles by becoming big hurdles to the target of consumer acceptance. In that case, industry tries to innovate things, which can jump over that hurdles. Some of […]
Difference Between Nominal and Ordinal
Nominal vs Ordinal People use numbers for different purposes. Ancient people needed numbers to count their belongings. So they invented counting numbers. As technology developed, the human needs became complex, and they needed different identifications for different objects. The number systems were developed or modified according to their needs. In statistics, different type of numbers […]
Difference Between Financial and Taxable Income
Financial vs Taxable Income Income is simply the total revenue for a period of time. From a business point of view, survival of an entity depends on its income or revenue. Income is expressed for a specific period. For example, one may say that my monthly income is $2000, or a company may say we […]
Difference Between Discrete Function and Continuous Function
Discrete Function vs Continuous Function Functions are one of the most important classes of mathematical objects, which are extensively used in almost all sub fields of mathematics. As their names suggest both discrete functions and continuous functions are two special types of functions. A function is a relation between two sets defined in such a […]
Difference Between Linear Equation and Quadratic Equation
Linear Equation vs Quadratic Equation In mathematics, algebraic equations are equations which are formed using polynomials. When explicitly written the equations will be of the form P(x) = 0, where x is a vector of n unknown variables and P is a polynomial. For example, P(x,y) = x4 + y3 + x2y + 5=0 is […]
