## Normal Probability Distributions

Normal Probability Distributions Intro:

## Normal Distribution Probability Function:

Definition of Normal Distribution Probability Function:

The concept “probability of X=x” is replaced by the “probability density function fx( ) evaluated at X=x”
A picture of this function with X=x plotted on the horizontal and fx( ) evaluated at X=x” plotted on the vertical is the familiar bell-shaped (“Gaussian”) curve.

## Mathematical Statistics and Its Importance

In mathematical statistics it is frequently necessary to deal with hypothetical distribution functions. The fundamental materials with which a statistician operates are numbers.

## The Statistics Involved Behind Growth Percentile Chart

The development of statistics has involved everything into it. From stock market to clairvoyant testing, from rolling of a dice to growth percentile chart nothing can go without statistics. What actually does statistics do? Well, in simple words we can say it just provides a mathematical platform to present experimental data. Not to mention observational data.

## Different Types of Averages

In this article. I will discuss different types of averages and why averages becomes an import.

## Trapezodial and Simpson Rule of Numerical Integral Approximation

In this article I will discuss, how to get the area under a curve without integration with approximation methods like Simpson rule and Trapezodial Rule.

## Statistical Test for Normal Distribution Assumption

This article will discuss the importance of normal distribution in statistical test process and the methods to test normal distribution for any data set whether it is small or large sample size.
