Time: 13:00 – 14:15

Host: Banu Yobaş
Abstract:
In any data science tasks, exploratory data analysis (EDA) is an indispensable step to take before diving into machine learning or statistical modeling. This is true even if the questions are handed to you on a platter, because you always need to make sure the data are really what they are claimed to be and that there are no obvious problems. To put EDA in context, the Data Science steps are: Obtain data, Clean and load data; Exploratory Data Analysis; Model building; Model evaluation; Data visualization and presentation. EDA methods are used for describing the data by means of statistical and visualization techniques to bring important aspects of that data into focus for further analysis.
This seminar starts with a brief introduction to exploratory data analysis methods. Then it examines a set of real world data by using these methods taken from official TURKSTAT data. A short explanation of a few very simple methods, such as coded-table, stem-and-leaf, five-point-summary and box-plot, is given and they are implemented on the data.
