How did Gauss come up with the normal distribution?
Relying on previous works of Pascal (combinatoric triangle and Binomial distribution) he identified this distribution as a bell shaped curve lying symmetrically around the mean. He also identified the standard deviation as a measure of spread of samples around the mean.
How was the normal distribution discovered?
The normal approximation to the binomial distribution for 12 coin flips. The smooth curve is the normal distribution. This same distribution had been discovered by Laplace in 1778 when he derived the extremely important central limit theorem, the topic of a later section of this chapter.
How did the normal distribution get its name?
The normal distribution is often called the bell curve because the graph of its probability density looks like a bell. It is also known as called Gaussian distribution, after the German mathematician Carl Gauss who first described it.
How do you interpret a Gaussian distribution?
The graph of the Gaussian distribution depends on two factors – the mean and the standard deviation. The mean of the distribution determines the location of the center of the graph, and the standard deviation determines the height and width of the graph.
Who discovered the standard normal distribution?
Carl Friedrich Gauss
The normal distribution is a probability distribution. It is also called Gaussian distribution because it was first discovered by Carl Friedrich Gauss. The normal distribution is a continuous probability distribution that is very important in many fields of science.
Who discovered the equation for the normal distribution?
The normal curve formula first appeared in a paper by DeMoivre in 1733. He lived in England, having left France when he was about 20 years old.
Is normal distribution named after a person?
Some were derived from persons associated with the distribution, e.g. Laplace ‘s second law and the GAUSSIAN law. Stigler remarks in his “Stigler’s law of eponymy” (see EPONYMY) that as the distribution has never been called after Abraham De Moivre, who worked on it in 1733, we may conclude that he was its originator.
When did Gauss discover the normal distribution?
1809
The term “Gaussian distribution” refers to the German mathematician Carl Friedrich Gauss, who first developed a two-parameter exponential function in 1809 in connection with studies of astronomical observation errors.

Who invented the normal distribution curve?
What is the origin of the name normal distribution?
NORMAL Distribution: Origin of the name. The NORMAL distribution has been studied under various names for nearly 300 years. Some names were derived from ERROR, e.g. the law of error, the law of facility of errors and the law of frequency of errors.
What is the probability density of the standard Gaussian distribution?
The probability density of the standard Gaussian distribution (standard normal distribution) (with zero mean and unit variance) is often denoted with the Greek letter ϕ {\\displaystyle \\phi } (phi). The alternative form of the Greek letter phi, φ {\\displaystyle \\varphi } , is also used quite often.
How did Gauss contribute to the development of mathematics?
The year 1796 was productive for both Gauss and number theory. He discovered a construction of the heptadecagon on 30 March. He further advanced modular arithmetic, greatly simplifying manipulations in number theory. On 8 April he became the first to prove the quadratic reciprocity law.
What is the Gaussian curve in statistics?
The Gaussian curve is a continuous random variable X with mean μ and standard deviation σ. The curve is unimodal and symmetric around the mean, that is, the graph is in the form of a bell. The highest frequency value, the fashion, coincides with the value of the mean and the median.
