本书保持了第1版的特点:作为统计学的入门教材,对数学基础知识的要求较低;用丰富、新鲜的例子说明统计学的概念、原理和运算程序,使全书极具趣味性和引人入胜;同时计算机、互联网以及多媒体教学手段的合理充分的使用,改变了统计学课程教学中原有的面貌,使学习和掌握统计学变得生动、活泼和十分容易。
全书内容包括数据的采集、整理与概括,变量之间的相关关系与分析,概率与随机变量,随机变量的数字特征,点估计和区间估计,回归分析与方差分析等内容。本书的特点是以讲统计学为主,概率论的内容服从和服务于统计学,占很小部分,而且两者穿插结合得如此恰当、完美,令人佩服。本书前四章讲抽样调查,把问题讲得很清楚、很好懂,是国内教材中不多见的。本书有两章讲分类变量之间的关系与分析,也是国内教材中不安排或很少安排的,而实际上这部分内容是很有用的。
全书自成体系,对统计学的原则和概念叙述得相当清楚和准确。书中的框图、小结等也使本书增色不少。
本书第2版比第1版在各章节中适当增加了一些内容和例子。各章节的习题有所增加,某些章节中增加了“打开计算机”的环节,为读者提供通过计算机掌握统计概念的手段。书末的光盘提供的内容要比第1版的光盘内容丰富许多。对全书的主要内容已作出PowerPoint,可直接用于双语教学。同时光盘中有数据和用各种统计软件解决实例的程序。
