主にクロス表(分割表)分析をしようかなと思いはじめましたが、あまりクロス表の分析はできず。R言語の練習ブログになっています。

 This post is following of above post.

In this post, let's make some graphs to see data distributions.

First, let's see overall student_mobility data histogram.

f:id:cross_hyou:20210718080939p:plain

f:id:cross_hyou:20210718080949p:plain

We see there are a few outliers over 40 area.

Next, let's see iso numbers bar chart.

Approximately one thirds countries have 10 years data.

How about year?

f:id:cross_hyou:20210718081852p:plain

We see there are no observations between 2006 to 2009.

Let's see student_mobility in detail, firstly, density plot.

Next, boxplot.

CDF

f:id:cross_hyou:20210718082323p:plain

Student Mobility by ISO

f:id:cross_hyou:20210718082426p:plain

f:id:cross_hyou:20210718082437p:plain

We see LUX(Luxenbrug) is the outlier.

f:id:cross_hyou:20210718082554p:plain

f:id:cross_hyou:20210718082605p:plain

We see median value is increasing slowly.

That's it. Thank you!
