Telling actionable stories with dataPhoto by Kyle Glenn on UnsplashIntroductionIn this article, I will share four common mistakes in data exploration and how you can avoid them.Exploratory data analysis (EDA) is the discovery of trends and patterns in data using graphical representations and summary statistics. Popular graphs for EDA include scatter plots, bar charts, histograms, donut charts, and heat maps. In addition, summary statistics which are measures for describing a dataset include count, mean, median, standard…
