In this blog, I want to perform Exploratory Data Analysis with Facebook dataset. This dataset contains almost 100,000 users and it varies from age, birthday,gender, to likes, mobile likes, etc..

Well this isnâ€™t actually a real Facebook dataset. But this pseudo data is provided by Data Analysts at Facebook. So we can be assured itâ€™s as good as the real one. This Exploratory Data Analysis ranging from my experience from Udacity Course, Exploratory Data Analysis with R, in which I acquired the dataset. You should check it, itâ€™s really recommended course.

Here I generate the html using Knit HTML with Rstudio. the code is as given.

Overview

Now, to get better at analyzing at the dataset, itâ€™s good to have all summary that we need to do this analysiz. First, I will do some basic summary to get better understand at the dataset. Here the dataset contain the words â€˜dobâ€™, which means data of birth.
