This is an expository subject that aims to present the fundamental concepts of Exploratory Analysis – thus allowing the understanding of the main mathematical and statistical tools used in understanding and analyzing data sets – and the main concepts of Data Visualization – in order to develop the training for the construction of good graphics, both exploratory and explanatory/communicative. In this sense, the subject will cover the following topics: Types of variables. Main measures of centrality and dispersion. Data cleaning, missing data, outliers. Descriptive statistics. Hypothesis testing. Clustering: k-means and hierarchical clustering. Types of graphs. Interactive graphics. Design principles and presentation of results. Tools: R: ggplot2, ggthemes, skisse. Python: matplotlib, plotly, seaborn, and bokeh Tableau and Power BI.
