Normaalimuuttujia
Normaalimuuttujia, often referred to as normal random variables, are a fundamental concept in probability theory and statistics. They are characterized by their bell-shaped probability density function, which is known as the normal distribution or Gaussian distribution. This distribution is defined by two parameters: the mean (μ) and the standard deviation (σ).
The normal distribution is symmetric around the mean, with the peak of the curve at the mean
Normaalimuuttujia are commonly used in various fields due to the Central Limit Theorem, which states that the
In statistical analysis, the normal distribution is often used to model errors and uncertainties in measurements.
However, it is important to note that not all data follows a normal distribution. In such cases,
