This makes the data more natural for the human mind to comprehend and therefore makes it easier to identify trends, patterns, and outliers within large data sets. Model building and pattern mining: Depending on the type of analysis, data scientists may investigate any interesting data relationships, such as sequential patterns, association rules, or correlations. In 1786, William Playfair, a Scottish economist, published The Commercial and Political Atlas, which contained a variety of economic statistics presented in graphs. Every dataset is unique, and the identification of trends and patterns in the underlying the data is important. These can be studied to find specific information or to identify patterns, known as trends, in whole groups of data. EDA aims to spot patterns and trends, to identify anomalies, and to test early hypotheses. that can be found within it. Students apply their understanding of patterns and relationships when solving problems in authentic contexts. Today's World.
