N a function representing the relative distribution of frequency of a continuous random variable from which parameters such as its mean and variance can be derived and having the property that its integral from a to b is the probability that the variable lies in this interval. Its graph is the limiting case of a histogram as the amount of data increases and the class intervals decrease in size 概率密度函数 (Also called density function) [statistics] → compare cumulative distribution function, frequency distribution
Well, it depends on what you know about the measurements' probability density function (PDF).
它依赖于您对度量值的概率密度函数(probability density function, PDF)的认识。
Figure 1 shows a typical normal probability density function, so called because most observations fall into this sort of distribution.
图1显示了一个典型的正态概率分布函数，这样命名是因为绝大多数值都属于这个分布范围内。
Figure 1: Normal probability density function, which illustrates that actual observations may vary from the expected (or average).
图1：正态概率分布函数，它表明实际的观测值可能会偏离期望值(或者平均值)。
