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 isn’t actually a real Facebook dataset. But this pseudo data is provided by Data Analysts at Facebook. So we can be assured it’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, it’s really recommended course.
Here I generate the html using Knit HTML with Rstudio. the code is as given.
Now, to get better at analyzing at the dataset, it’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 ‘dob’, which means data of birth.
