正态分布是自然界最常见的一种连续型概率分布,许多分布可以用正态分布来近似描述.它虽是进入高中数学的新内容,但因与其相关的试题背景新颖、生活气息浓厚,也倍受命题者重视.高考常以选择题、填空题的形式出现考查正态分布,难度不大,但也不容忽 Normal distribution is the most common kind of continuous probability distribution in nature, and many distributions can be approximated by normal distribution.Although it is a new content entering high school mathematics, because of the new background of the related questions and the strong flavor of life, Highly regarded by the proponents.College often to multiple-choice questions, fill in the blank form to test the normal distribution, is not difficult, but also not to be ignored
