PDFkäyrän
PDFkäyrän is a Finnish term that translates to "PDF curve" or "PDF graph." It refers to a visual representation of the probability distribution of a continuous random variable. In simpler terms, it's a way to show how likely different values are for a given measurement or outcome. The area under the PDF curve between two points represents the probability that the random variable will fall within that range. The total area under the entire PDF curve is always equal to 1, signifying that there is a 100% probability that the variable will take on some value. Different probability distributions have distinct PDFkäyrän shapes, such as the bell-shaped curve of the normal distribution or the U-shaped curve of a uniform distribution. This concept is fundamental in statistics and probability theory, used for understanding, analyzing, and predicting outcomes in various fields including science, finance, and engineering.
