绘制定性问题与定量问题

Question

我和我的学生一起进行调查，我想在R中创建一个图表来绘制具体问题。我特别感兴趣的是看到这两个问题之间的关系：

Q5. How do you find the pace of the lecture?
a) Way too fast
b) A bit too fast
c) About right
d) A bit too slow
e) Way too slow

Q8:Outside of lectures how much time a week do you devote to this class?
 _________ (hrs)

在这种情况下，哪种R图表是可取的？

Answer 1

我想说boxplot()可能适合这里。例如：

blur

或者可能是积分图：

paces <- c('wayslow','slow','right','fast','wayfast');
set.seed(1);
N <- 30;
df <- data.frame(pace=factor(sample(paces,N,replace=T),paces),outside=runif(N,5,30));
boxplot(outside~pace,df,xlab='Pace of Lecture',ylab='Hours Outside of Lecture');
