Partial Fractions maths
In this series of articles we shall explore partial fractions. First we shall look at the basics of adding and subtracting algebraic fractions, then explore fractions with two linear fractions, partial fractions with three...

Normal Approximations
In the following series of articles we shall explore normal approximations. We shall explore continuity correction, approximating a binomial distribution by a normal distribution, approximating a poisson distribution by a normal distribution, and choosing...
Choosing the right distribution model
This article continues from the previous article so it may be a good idea to go through it. This article covers when to use the continuous uniform distribution model. We shall explore these situation...
Properties of a continuous uniform distribution
This article continues from the previous article. It may be a good idea to go through it before attempting this. This article explores properties of a continuous uniform distribution. We shall look at the...
Continuous uniform/rectangular distribution
This article explores the continuous uniform/rectangular distribution. Prior knowledge of continuous random variables will be useful here. The continuous random variable X with probability distribution function (p.d.f); [IMAGE] where a and b are constants...
Lower, Upper, and Inter quartile range of a continuous random variable
This article is a continuation from the previous article. This article explores the lower quartile, upper quartile and inter-quartile range of a continuous random variable; Key Points If X is a continuous random variable...
Continuous uniform distribution
In this series of articles we’re going to explore the continuous uniform distribution. In the following articles we shall look at how to decide when to use the continuous uniform distribution, how to derive...
Mode of a continuous random variable
This article is a continuation from the previous article. It may be a good to read through it before attempting this article. This article explores the mode of a continuous random variable. The mode...
Probability density mean and distribution
This article is a continuation from the previous random variables article. This article covers mean and variance of a probability density function. First we shall discuss a few key points before actually looking at...
Cumulative distribution function
This article is a continuation from the previous continuous random variables article. It may be a good idea to read through it before attempting this section. This article covers cumulative distribution for continuous random...
