### Difference Between Laplace and Fourier Transforms

// Dec 7th, 2011
Laplace vs Fourier Transforms   Both Laplace transform and Fourier transform are integral transforms, which are most commonly employed as mathematical methods to solve mathematically modelled physical systems. The process is simple. A complex mathematical model is converted in to a simpler, solvable model using...

### Difference Between Binomial and Normal Distribution

// Nov 7th, 2011
Binomial vs Normal Distribution   Probability distributions of random variables play an important role in the field of statistics. Out of those probability distributions, binomial distribution and normal distribution are two of the most commonly occurring ones in the real life. What is binomial distribution? Binomial...

### Difference Between Orthogonal and Orthonormal

// Nov 3rd, 2011
Orthogonal vs Orthonormal   In mathematics, the two words orthogonal and orthonormal are frequently used along with a set of vectors. Here, the term ‘vector’ is used in the sense that it is an element of a vector space – an algebraic structure used in linear algebra. For our discussion, we will consider...

### Difference Between Simple Random Sample and Systematic Random Sample

// Oct 30th, 2011
Simple Random Sample vs Systematic Random Sample   Data is one of the most important things in statistics. Due to practical difficulties it will not be possible to make use of data from a whole population when a hypothesis is tested. Therefore, data values from samples are taken to make inferences about a population....

### Difference Between Derivative and Differential

// Oct 28th, 2011
Derivative vs Differential   In differential calculus, derivative and differential of a function are closely related but have very different meanings, and used to represent two important mathematical objects related to differentiable functions. What is derivative? Derivative of a function measures the rate at which...
