**课程名称：** 频率分布掌握：第二部分 **课程概要：** 本课程是关于频率分布的进阶学习。您将学习如何根据不同类型的数据集构建分组频率分布表。具体内容包括： * **二氧化硫浓度数据：** 学习如何处理空气中二氧化硫浓度的分组频率分布表，其中已给出类区间。 * **抛硬币数据：** 学习如何准备关于抛硬币次数及其出现正面次数的数据的频率分布表。 * **圆周率 (π) 数据：** 学习如何根据圆周率的小数位数据，形成频率分布表。 * **观看电视节目时间数据：** 学习如何根据学生上周观看电视节目时长的不同，构建分组频率分布表。 * **汽车电池寿命数据：** 学习如何构建关于汽车电池寿命的数据的分组频率分布表。 此外，课程还将深入讲解在处理大量数据时，如何将数据进行分组（称为“类”或“组距”），以及如何确定**类的大小（类距或组距）**。您将理解**下限（最小数）**和**上限（最大数）**在每个分组/类中的含义。
1. How to make a grouped frequency distribution table where the data in respect of concentration of sulphur dioxide in the air of a certain city for the last few days is given along with class intervals.2. How to prepare a frequency distribution table in respect of the data of number of heads occurred when a few coins were tossed many times simultaneously.3. The students will learn to form a frequency distribution table when the data in respect of the value of π up to many decimal places is given.4. How to form a grouped frequency distribution table when the data in respect of many students is given who watched the TV programmes for different hours in the previous week.5. The students will also learn to construct a grouped frequency distribution table where the data in respect of lives of few car batteries is given.6. When the large amount of data is to be presented, we can condense the data in to groups and these groupings are called "classes" or "class-intervals" and their size is called the class-size or class width. In each of these groupings/classes, the least number is called the lower class limit and the greater number is called the upper class limit.
