一、数据概览

1.背景描述

该数据集整理了从1896年雅典奥运会至2016年里约热内卢奥运会120年的奥林匹克运动会的历史数据。

需要注意的是，在1896年-1992年期间，冬季奥运会与夏季奥运会都是在同一年举行的。在这之后，冬季与夏季的奥运会才被错开举办，冬季奥运会从1994年开始4年举办一次，夏季奥运会从1996开始4年举办一次。大家在分析这些数据时，经常会犯得一个错误就是认为夏季与冬季奥运会是一直错开举办的。

• 受疫情影响，2020东京奥运会将延期至2021年举行；

• 虽然延期，但此次奥运会依旧会沿用「2020东京奥运会」这个名称；

• 这也将是奥运会历史上首次延期（1916年、1940年、1944年曾因一战，二战停办）；

2.数据说明

• 文件列表 该数据集包含两个文件：

• athlete_events.csv ：参赛运动员基本生物数据和奖牌结果

• noc_regions.csv ： 国家奥委会3个字母的代码与对应国家信息

3.属性描述

文件athlete_events.csv中包含15个字段，具体信息如下： ​

每一行代表的是一个参加个人比赛运动员

文件noc_regions.csv中包含3个字段，具体信息如下：

4.数据来源

数据集源自于kaggle平台用户分享，
基于证书 CC0: Public Domain 发布，
具体信息内容源自
https://www.sports-reference.com/

二、数据集可探索、研究的方向

可以从以下几个方面来探索奥林匹克运动会的演变历程：

• 历年来 男女参赛运动员的表现如何？

• 那不同地区？

• 不同运动项目？

• 不同比赛项目？

三、可视化分析
