有没有免费的数据分析器可以帮助信息可视化?
我准备了一份评估软件的调查问卷并将其提交给n个人。 问卷有很多问题,全部只有一个选择,例如:
- 您的年龄是多少? (13-15) (19-25) (26-35) (35岁以上)
- 您的资格是什么? (大学生) (已毕业) (博士)
.... 对以下方面发表从 1 到 4 分的意见: a1 a2 ... 我复制了 Excel 和 Mysql 数据库中的所有答案,现在我需要找到例如之间的相关性。年龄和各个方面的评分。 有没有一个免费的工具可以在 Linux 上执行此操作,可以帮助我可视化相关性?例如。大多数 13 到 18 岁之间的人评价方面 1 不好,19-25 相当差,26-35 相当好...
我知道双变量、三变量数据的多种可视化类型(例如散点图),但我不知道如何获取它们。
请原谅我的英语最差,我希望您能理解我的问题...提前致谢!
I prepared a questionaire for evaluating a software and submitted it to n people.
The questionaire has many questions, all with a single choice, like following:
- What's your age? (13-15) (19-25) (26-35) (over 35)
- What's your qualification? (college student) (graduated) (phD)
....
Express an opinion with a rateing from 1 to 4 on the following aspects:
a1
a2
...
I copied all answer both in Excel and in a Mysql Database and now I need to found correlations between eg. age and ratings for each aspect valued.
Is there a free tool to do this for Linux, that can help me visualizing correlations? Eg. most people between 13 and 18 evalued aspect1 bad, 19-25 quite bad, 26-35 quite good...
I know many types of visualizations for bivariate, trivariate data (eg. scatterplots) but I don't know how to obtain them.
Excuse me for my worst english, I hope you have understood my issue... thanks in advance!

LibreOffice 具有从表格制作图表的内置功能,就像在 Excel 中一样。尝试使用它:)
请参阅 http://help.libreoffice.org/Common/Inserting_Charts 和该页面上的链接以获得更多帮助。
LibreOffice has built in features to make graphs from tables, like you can do in Excel. Try using that :)

R 是一个顶级的统计程序,但我不确定这正是您想要的为了。
R is a top-drawer statistical program, but I'm not confident that's quite what you're looking for.
